Question

if in a circuit the resistance is doubled and the potential difference remains same how does the current change derive this using Ohm's law.
pls give me proper answer​

Answer 1

Answer:

since V = IR

V/I = R

If resistance is doubled then current is halved.

Answer 2

Answer:

Explanation:

According to Ohm's law

V = IR

I = V/R

according to condition

R' = 2R

so

I' = V/R'

I' = V/2R

I' = I/2

hence current will be reduced by half.
