What is resistor ? (Resistor kya he?)

What is resistor ?

"Resistor ek esa electronics component he jo kisi circuit me dhara(current) ke bhne ka virodh krta hai". current ko control krne ke aadhar pr resistor ko alag alag value ka bnaya jata he . Jise iska Resistance khte he. Ise "R" se denote kiya jata he. Resistance ka matrk (unit) OHM (Ω) hota hai.
(That component which oppose flow of current is called resistor)
Resistor ki value 0Ω se lake kai mega Ω tk hota hai.

Example ke tor pr kh skte he ki ek resistor Road me bne breaker ke sman hota he. means jab koi gadi breaker ke njdeek ati he to gadi ki speed kam ho jati he (ya kam krni hoti he) theek usi parkar resistor bhi breaker ke sman hota he jo current ki speed ko seemit kr deta he.
Hindi me resistor ko प्रतिरोध kha jata he. Iske value Ω me jitni jyada hogi ye yh uttna hi current ke flow hone ka virodh krega .
Resistor ka symbol niche figure me diya gya he.

Symbol of resistor (both are resistor symbol)

Resistor do parkar ke hote he

1. Fixed resistor
2.Variable resistor

Fixed resistor me uski valu fixed rhti jese - 100Ω, 1kΩ, etc.
Variable resistor ki value fixed nhi hoti he arthat is resistor ki value ko ghtaya ya bdhya ja skta he.




Symbol of Variable resistor

 Kisi bhi circuit me bhle hi koi component use ho ya na ho lakin resistor jroor hota he. Chote se bde hr circuit me resistor jroor hota he.

Resistor ko electric & electronics dono circuits me use kiya ja skta hai.

Resistor alag alag watt ke bhi hote he jise circuits ki specification ke adhar pr use kiya jata he.  

 For example : 1/4 watt, 1/2 watt,  1watt, 2watt, 5watt, 10 watt etc.

Niche resistor (Through hole resistor & SMD Resistor) ka  3D view diya he jise dekh kr app resistor ka identification watt ke adhar pr kr skte ho.

Through hole Resistor 

                                                  

SMD Resistor 

 Hm ne ab tk pdh liya he ki resistor ka use hm kha krte hai, uska symbol kesa hota hai or vh dekhne me kesa hota hai.
Ab me apko btauga ki resistor ki colour codding kese ki jati he. Mean colour codding ke aadhar pr resistance ki value kese measure ki jati he.
Friends app ne upper diye figure me dekha hoga ki resistor ke surface ke upper alag alag colour ke band bne he, is colour band ke aadhar pr resistor ki value calculate ki jati ki resistor kitne ohm ka hai.

Vese to THT resistor ki value nikalne ke kai treeke he jese - Using Multimeter , using LCR 


Pr is post me ham resistor ki value ko colour codding se nikalege.

Resistor colour codding

Resistor colour codding me  12 colours aate he unke combination se different - different value ke resistor bnaye jate he.

S.N.  COLOUR'S NAME  DIGIT MULTIPLIER    

1.                  Black                  0           10^0 = 1

2.                  Brown                1           10^1 = 10

3.                  Red                    2           10^2 = 100

4.                 Orange               3           10^3 = 1000

5.                 Yellow                4           10^4 = 10000

6.                 Green                 5          10 = 100000

7.                  Blue                   6          10^6 = 1000000

8.                  Violet                 7          10^7= 10000000

9.   Grey                                  8         10^8=100000000

10.               White                 9                    10^9 = 1000000000

11                Silver                   -            0.01

12.               Gold                   -            0.1                         

Yha resistor ki colour codding table same colour se di gyi he ise dekh kr app kisi bhi resistor ki resistance value asani se pta kr skte ho.

Chaliye ab example ke tor pr kisi resistance ki value nikalte he -

Mana kisi resistor ka first band     -    Brown

                             Second band     -      Black   

                                        Third band     -  Red     

 Value of resistance -  Yha first do digit ko sheedhe utarege or third band ke liye multiply kte he

Is parkar -

               Value of resistance - 1    0      ×  100

                                           

                 Value of resistor  -             10×100 = 1000 Ω   or  1k Ω

 Is parkar kisis bhi resistance ki value colour codding ke adhar pr kr skte.

Agr apko  is article se related  kisi bhi parkar ka question krna ho to niche diye comment box me kr skte he.

What is Capacitor ?

 "Capacitor ek esa electronic component he jo kisi circuit me electric charge  (vidhut avesh) ko store krta he".

Electronics ka main component capacitor (संधारित्र ) hi he. Capacitor  do terminal ka passive component hota he. Esa koi bhi circuit nhi hoga jisme jisme capacitor use na hota ho, circuit chhota ho ya bda ho  capacitor ka use usme hota hi he.

Capacitor ka pryog electronics ke sath sath electric circuit me bhi kiya jata he prntu jyadatr use electronics circuit me hi kiya jata he.

koi bhi capacitor circuit me AC signal (Ya current) ko aage ki or pass krta he tatha DC current ko aage ki or jane se rokta  he arthat DC current ko block kr deta he.

Is parkar Capacitor AC signal ke liye Short circuit (Low resistance) ki trh kam krta he or DC current ke liye open circuit (High Resistance) ki tarh kam krta he.

Capacitor is an electronics component which stores electric charge in the circuit.

Capacitor ko 'C' se denote krte he, iski value ko (unit) 'Fared' me mapa jata he.
Capacitor ka symbol niche figure me diya gya he  →
                                   

Symbol of fixed and variable capacitor


 Construction -  Capacitor me do metal ki plates hoti he or dono plates ke beech me dielectric (Pravedhutank) pdarth  ko rkha jata he.
Jab capacitor ke ek terminal ko battery ke possiteve terminal se tatha capacitor ke doosre terminal ko battery ke negative terminal se connect krte  he to capacitor ke ek plate me positive charge or dosri plate pr negative charge jma ho jate he. Iska matlb yh hota he ki capacitor me charge store ho jata he jo voltage ko hta lene pr bhi salo ke liye iseme charge store rhta he.
agr capacitor ko discharge krna hota he to capacitor ke parallel me koi resistor lgaya jata he.
                         formula of capacitance                                                    C = Q/V

                                     and                                                                            C = દA/D
Capacitor ki jo value hoti he use capacitance me mapa jata he.
Capacitor ka 3D view figure ke madhyam ye niche diya gya he
Note - Kisi bhi circuit me lge capacitor ke terminals ko ek sath chhoona nhi chahiye esa krne se itna jor ka shock lg  skta he ki insan ki mot bhi ho skti he.


Use of Capacitor :::

• Electronics circuit me filter ke roop me
• Oscillator bnane me
• Scientific field me
• Temporary battery ki trh
• Energy storage
• Coupling me etc.

 
Types of Capacitor -
Capacitor 3 parkar ke hote he ;;;
1- Value ke adhar par

(a) fixed capacitor --
is ki value fixed hoi he jese - 50uF, 100uF, 470uF, 100nf, 22pf etc.

(b) Variable capacitor --
is capacitor ke capacitance ko ghtaya ya bdhaya jata he, jese- 10 uf - 100uf etc.

2- Pol ke adhar par

(a) polar capacitor
In capacitors me ek terminal positive (+ve) v doosra terminal negative (-ve) hota he, terminal ke adhar par hi isko circuit me +ve ko +ve se v  -ve ko -ve voltage se connect kiya jata he.
Electrolyte capacitor ek polar capacitor hota he.

(b)  Non-Polar capacitor ---
Is parkar ke capacitor me koi fixed pole (dhurv) nhi hota he, islie ise circuit me kisi bhi treeke se connect kr skte he,

3- Construction ke adhar par (size v shape ke adhar pr)

• Electrolyte capacitor
• Ceramic capacitor
• Mica Capacitor
• Polyester capacitor
• Film capacitor

kisi bhi capacitor ko construction ke adhar par hm dekh kr phchante he ki yh konsa capacitor he or circuit me unhe unki properties adhar pr connect kiya jata he.
chitr ke madhyam se app capacitor ko ache se pahchan skte ho.
Niche sbhi parkar ke capacitors ka figure diya gya he ⬇️⬇️




electrolyte Capacitor 

In sbhi parkar ke capacitor ki working same hoti he, sbi me do metal ki plates hoti he. Lekin alg-alg parkar ke capacitors me difference inki plates ke beech me rkhe dielectric & construction  ka hota he. In sbhi parkar ke capacitor ka use inki characteristics ke adhar pr hota he

What is Inductor ? (Inductor kya he?)

Inductor ek passive electronics component he jo kisi electrical energy ko magnetic field ke roop store krta he 

An Inductor is a passive electronic component that store electrical energy in the form of magnetic field in the circuit.

Inductor ke khoj krta Joseph Henry he. 

Jab kisi bhi conductor wire me koi current flow hoti he to conductor ke charo traf ek magnetie field generat ho jata (Means conductor ek chumbk ki trh kam krne lgta he). Isi base pr inductor ka nirmad kiya jata he.

Inductor ke magnetic field generat krne ki prosess ko Inductance kha jata he. Inductor ko 'L' se demote kiya jata he. Iski Unit (Matrk)  Henery (H)  he.

For example -  1H, 20 mH,  100uH etc. 

 Ise hindi me प्रेरक khte hai.

Electronics Industry mai koi electronics product development karne ke lye Circuit design R&D department ke andar aata hai. R&D sbse first process hoti hai jo top level mai atai hai. Electronics circuit ko ek qualified Electronics Engineer bnata hai. 

           Circuit design ke liye Circuit design software ya PCB design software ka use kiya jata hai.

Circuit design ki process ko niche step by step btaya gya hai.   

(1).  Components symbol   -   Ye symbol PCB design software ki librarey mai mil jatae hai or software ki help se hme khud ke symbol ki drawing bn skte hai. Symbol drow ho jane par iski file ko save kar lete hai.

(2).  Circuit Diagram (schematic Diagram) -  

Symbol create ho jane ke bad, un symbols ko jinki hme circuit mai need hai unhe Schematic sheet  mai place kar dete hai.

(3) Circuit Diagram (Schematic)

                   

                      Iske bad components ka unki properties ke according arrengment kiya jata hai. Iske bad software ke tool ki help se components ko apas mai connect kar liya jata hai. Schematic sheet ban jane ke file ko save kar liya jat hai.

 (3). Foot Print -        Yah circuit design ki software mai 3rd process hai. Foot prints components ki actual size hota hai. Inhe components ki dimension ke according bnaya jata hai. 

(4) Foot print

                 

      Maximum foot print hme software ki librarey mai mil jate hai. Jo foot print librarey mai nhi milte une tool ki help se drow ka liya jat hai. SMD components ho ya through hole components ho dono ko unke size ke according unka foot print bna liya jata hai. Iske bad foot print ki file ya sheet ko save kar liya jat hai.

 (4). Layout -          Layout designing, circuit design ki 4th or last process hai. isme schematic ke according components ka arregment kiya jata hai. Ab hme PCB ka size or shape ko draw karna hota hai jiske andar hme pure circuit ka layout bnana hota hai. 

(5) PCB Layout

                               Ek achchha PCB designer  kam area mai kafi bde circuit ko bnane ki kosis karta hai. PCB design ke bhut sare rules hote hai, jinhe flow karke ek designer ek beautiful circuit bnata hai. Ab iss file ko bhi save kar liya jat hai. 

      3D View of PCB -     Figure (6) mai PCB ka 3D view diya gya hai, hmari final PCB figure(6) ke sman bnti hai, Iss circuit mai sare components SMD ke mount kiye gye hai.

(6) 3D View of PCB

Sari files ko save karte time  un sbhi files ko same  nam se system mai save kiya jata hai. Fir uski Gerber file bna li jati hai. Yha pe PCB designer ka kam khatm ho jat hai.

                         

Upper di hui sari process ko follow karke ek complete electronics circuit  ka design kiya jata hai. In sari process ko complete karne ke liye vhut sare tools ki bhi kroot padhti hai sath hi companies ko Engineers and kusal employers ki jroort padhti hai.
