Question

In given circuit diagram resistance, voltage and

corresponding current are R, V and I respectively.

What would be the value of resistance if voltage

is doubled? Temperature remains constant.​

Answer 1

Voltage=V

Resistence=R

Current= I

We know,

V=I×R

=> R=V/I

So,

New Resistance=R'=2V/I =2R [ bcoz R∝V] (Ans.)
