Question

Some metal conductor has a resistance of 12ohm. When plugged into a circuit, the amount of heat 144J is released in 12s. What is the voltage at the ends of the conductors?​

Answer 1

Answer:

12V

Explanation:

E= power × time

Power = V^2/R

E = (V^2 * t)/R

144= (V^2 /12) × 12

144 = V^2

V= root of 144

V = 12V
