Question

The frequency of applied ac emf applied to an ac circuit is quadrupled What is the effect on the (i) resistance (ii) inductive resistance and (iii) capacitive resistance.

Answer 1

• Resistance will not change
• Inductive resistance $X_L=2\pi fL$ so it will become $4$ times when $f$ is quadrupled.

capacitive resistance $X_c=\frac{1}{2\pi fc}$ so it will become $\frac{1}{4}$ times of its old value.
