Question

Proof of equivalent resistance in parallel combination

Answer 1

Answer:

Explanation:

In parallel combination of resistors, all resistors have the same potential difference. and current divides itself in these junctions.

       I =I1+ I2+ I3 +...........+In

     V/R = V/R1+ V/R2 +........+V/Rn

therefore

     1/R = 1/R1+ 1/R2 +....... 1/Rn
