Question

A charged 30 μF capacitor is connected to a 27 mH inductor. What is the angular frequency of free oscillations of the circuit?

Open in App

Solution

Capacitance, C = 30μF = 30×10⁻⁶F

Inductance, L = 27 mH = 27 × 10⁻³ H

Angular frequency is given as:

Hence, the angular frequency of free oscillations of the circuit is 1.11 × 10³ rad/s.
