Obtain the resonant frequency and Q-factor of a series LCR circuit with `L=3.0H, C=27(mu)F, and R=7.4 Omega`. How will you improve the shapness of resonance of the circuit by a factor of 2 by readucing its full width at half maximum?

Explanation

To solve the problem of finding the resonant frequency and Q-factor of a series LCR circuit with given values of inductance (L), capacitance (C), and resistance (R), we will follow these steps:

### Step 1: Calculate the Resonant Frequency (f₀)
The formula for the resonant frequency of a series LCR circuit is given by:

\[ f_0 = \frac{1}{2\pi\sqrt{LC}} \]
