A power line carries current 10 A and has resistance 2.0 $\Omega$. What is the power loss as heat in the line?
A) 200 W
B) 20 W
C) 10 W
D) 5 W

Question

Quizplus · Accepted Answer

The power loss due to resistance in a conductor can be calculated using the formula P = I^2 * R, where P is the power loss in watts, I is the current in amperes, and R is the resistance in ohms. Substituting the given values, P = 10^2 * 2 = 100 * 2 = 200 W.
