Question

The frequency of a.c. source is doubled. How do R, X_L and X_c get affected?

Answer 1

There is no effect of doubling the frequency of the a.c. source on R. Since X_L = 2πfL, the value of X_L becomes double on doubling the frequency of the a.c. source.
Further \(X_c = \frac{1}{2\pi fc}\)
∴ The value of X_c becomes half on doubling the frequency of the a.c. source.
