Question

if the potential difference between the end of a fixed resistor is halved the electric power will become

Answer 1

p=v²/R

since R is constant

p becomes 1/4 times when V is halved

Answer 2

If the potential difference between the end of a fixed resistor is halved, the electric power becomes one fourth of initial power.

Explanation:

The electric power of a resistor is given by :

$P=\dfrac{V^2}{R}$

Where

V is the potential difference

R is the resistance of the resistor

If the potential difference between the end of a fixed resistor is halved, the electric power becomes one fourth of initial power.
