Suppose the frequency of the source in the above example can be varied (a) What is the frequency of the source at which resonance occurs ? (b) Calculate the impedeance, the current and power dissipated at the resonant condition.

Explanation

To solve the problem step by step, we will break it down into two parts as indicated in the question.

### Part (a): Finding the Resonant Frequency

1. **Understanding Resonant Frequency**: The resonant frequency \( f_0 \) in an LC circuit is given by the formula:
\[ f_0 = \frac{1}{2\pi\sqrt{LC}} \]
