Question

The potential difference across a 4 ohm resistor is 20 V. Assuming all the energy dissipated is heat, how many joules of heat are produced in 10 seconds?
Options
A 1000 J
Correct Answer
B 100 J
C 0.100 J
D 10 J
Correct Answer

Option A is the correct answer.

Detailed Explanation

P = V2/R = (20)2/4 = 100 W. E = Pt = 100 x 10 = 1000 J.

Hint

P = V2/R = (20)2/4 = 100 W.
