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.

Dear readers if you have any question and suggestions related to my any post or My site (Electronics & Technology) so you can leave message in comment box. I will try to give answer of your questions in short time.

Thank you very much

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.

Inductor ka Electronic symbol v 3D figure niche diya he. ⬇️⬇️

Symbol of fixed inductor

Symbol of variable inductor

• 

  Inductor
  
  

Use of Inductor - 

• Oscilattor bnane me 
• Filters bnane me 
• Current smooth krne me
• Resonator me
• Tuned circuts me 
• Scientific purpose ke liye  etc.      

   

Toroid type inductor 

Inductor ke apne iss gun ke kard isee bnaii jane wali chije niche di he 

Transformer bnane me

Relay bnane me 

Motors bnane me 

Electricity generate krne me Turbine me etc. 

Main point for Inductor 🤔🤔🤔🤔🤔

• Ek inductor DC ko pass krta he or AC ko block krta he. Mtlb DC ke liye short circut v AC ke liye open circuit ka kam krta he. 
• Inductor Electromagnetic Inductance ke sidhant pr work krta he.
• Agr kisi inductor se current pass hoti he to vh ek magnet bn jata he. Tatha vh iron se bni chijo ko apni or attract krta he.
• Agr kisi winding se current flow hoti he or uske njdeek koi doosri winding late he to dossri winding me mutual inductance utpnn ho jata. Pr esa winding pr AC current gujarne pr hota he.
• Jab inductor ko emf. diya jata he to vh kafi lmbe time ke liye charge ho jati he. 
• Jab kisi coil me DC current pass hoti he to coil ke surrounding ek constant(Na privrtan hone wala)  megnetic field generate hota he or AC ke pass hone pe ek variable megnetic field utppn hota he 

   

Variable Magnetic field ki matra ko Magnetic flux khte he ise Φ se denote krte he.

Hence 
 Quantities of inductance.      L =  Φ/I

Other name of inductor 
Coil,  Chock, Filter, inductor 

Construction of inductor - 
Inductor ko kisi core (jese ferrite core) ke charo or kisi wire se winding krke banya jata he.  Application or power or inductance ke adhar pr inductor ka constitution alag alag treeke se kiya jata he. Jese Rode type inductor, Toroid type inductor etc.
Is parkar inductor ko fixed or variable dono parkar ka bnaya jata he.

Dependents of inductance - 

• Number of turns of wire
• Lengh of  wire 
• Radius of wire 
• Radius and lenth of coil 
• Core 
• Physical properties of wire and core.

Note -                                                                        1H    =  10^3 mH  = 1000 mH                            1H.     =  10^ 6 uH  = 1000000 uH               1mH   =  10^ 3 uH  = 1000 uH

Inductor  ko resistor ki trh series me do ya do se adhik inductor  connect kr  uska inductance bdhaya jata he v parallel me connect kr  inductance ko ghtaya jata he.
