Consider an ac circuit consisting of a power supply and a resistor. if the current in the circuit at time t is /, then the power delivered to the resistor is /, where r is the resistance. express the power in terms of .

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.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
