Question

100 J Heat is generated in a resistance of 4 ohm in 1
second. What is the
potential
difference of
the resistor​

Answer 1

hi friend

hope it will help

Answer 2

Answer:20V

We know that,

Heat = V^2 × t / R

100J = V^2 × 1sec. / 4ohm

V^2 = 100J × 4ohm / 1sec.

V^2 = 400

V = ✓400

V = 20V
