A `10 muF` capacitor is connected with `100V` battery.What would be the electrostatic energy stored ?

Explanation

### Step-by-Step Solution

**1. Definition of Series LCR Resonant Circuit:**
A series LCR resonant circuit consists of an inductor (L), a capacitor (C), and a resistor (R) connected in series. This circuit is designed to resonate at a particular frequency where the inductive reactance (XL) equals the capacitive reactance (XC).

**2. Expression for Impedance (Z):**
The impedance (Z) of the series LCR circuit can be expressed as:
\[ Z = \sqrt{R^2 + (X_L - X_C)^2} \]
