-If the source voltage changes to 100 V in Figure 12 -1, the true power is .
A)16 W 
B)4 W 
C)40 W 
D)40 mW

Quizplus · Accepted Answer

The true power (P) in a circuit is calculated using the formula P = V^2 / R. Assuming the resistance (R) is such that when the voltage (V) is 100 V, the power calculates to 40 W, option C is correct.
