Question

keeping the potential difference constant the resistance of a curcit is double , by how much does the current change?​

Answer 1

Answer:

the electric current is halved if potential difference is constant and resistance is doubled.

Explanation:

By ohm's law

V=IR

I=V/R

according to condition V=constant and resistance is doubled

Then,

I=V/2R

I=I/2 (because V/R = I by replacing V/R from

I=V/2R we have got I=I/2)

Therefore current is halved when Potential difference is constant and resistance is doubled
