Question

If the potential difference between the ends of a fixed resistor is halved, the electric power will become
(a) double
(b) half
(c) four times
(d) one-fourth; If the potential difference between the ends of a fixed resistor is halved, the electric power will become
(a) double
(b) half
(c) four times
(d) one-fourth

Answer 1

Answer:

option (d) is correct

Explanation:

We know that power dissipation by a resistance is given by v^2/r ... therefore if potential difference between the ends of a fixed resistor is halved. The power will become one-fourth....

Answer 2

Answer:

answer d is correct...........
