RC Circuit and its Formula

RC circuit is the combination of Resistor and Capacitor. It is an electrical circuit where resistor of resistance is connected in series with the capacitor of capacitance.

The characteristic frequenct has two applications. They are RC Circuit is used as filter and capacitor charge time.

The formula to get the characteristic frequency of the RC Circuit is follows:

f = 1/(2π * R * C)


R is the resistance of the resistor

C is the capacitance of the capacitor

f is the characteristic frequency

The capacitor charge time formula is t = R x C


Question: The capacitance and resistance in the RC Circuit are 52 Ω, 25 F. Find the characteristic frequency?


Given that

Resistance R = 52Ω

Capacitance C = 25 F

characteristic Frequency f = 1/(2π * R * C)

f = 1/(2π * 52 * 25)

= 12.2 x 10-8

Therefore, characteristic frequency in RC Circuit is 1.2 x 10-8 Hz.
