### What is Resonant Frequency?

The resonant frequency is the frequency observed in the LC circuit. It is a natural frequency of the system. The resonant frequency is defined as the frequency where the transfer function reaches its maximum value. The different types of resonances are electrical, optical, mechanical, orbital, and molecular. The formula to calculate the resonant frequency is as follows: f = 1/[2π * √(L * C)]

Where,

f is the Resonant Frequency

L is the Inductance

C is the Capacitance

**Example**

**Question: Determine the resonant frequency of an LC Circuit that has an inductor of 5 mH and capacitor of 4 µF.**

**Solution:**

Given that

Inductance L = 5 mH = 5 x 10-3

Capacitance C = 4 µF = 4 x 10-6

Resonant frequency is f = 1/[2π * √(L * C)]

f = 1/[2π * √(5 x 10-3 * 4 x 10-6)]

f = 1/[2π * 4.47 x 10-3

f = 0.0011254 MHz

Therefore, the resonant frequency is 0.0011254 MHz.
