Question:

A voltage V = 5 Cos \(15\pi \)t V flows through a resistor of 33 \(\Omega \). What will be the average value of current flowing through the circuit?

Options:

0.13

0.2

0.14

0.5

Correct Answer:

0.13

Explanation:

I = \(\frac{V}{R}\) = 0.2 Cos \(15\pi \)t A

I_avg = 0.636Io = 0.636 x 0.2 = 0.13 A
