Answer:
Option B. is the answer.
Step-by-step explanation:
The given question is incomplete; complete question has been given in the picture attached.
Current in the circuit at the time t is .
Power delivered to the resistor is
Where R = resistance
We have to express the power in the terms of cos2w.
Since formula to get the power in a circuit with resistance R and current I is given by
P = I²R
Therefore, power for the given circuit will be
P =
P = [Since sin²t = ]
P =
Therefore, Option B. will be the answer.
