Answer 2

Answer:

Resonance :

The resonance in an electric circuit is the condition when the various impedance of the circuit is in opposition and, in the end, cancels each other. Eventually, the input impedance and output impedance are equal.

The series resonance is the condition that occurs only in the case of a series RLC circuit. In series resonance, the value of the current is maximum possible for a set voltage. The frequency at which the resonance occurs is known as the resonant frequency.

Consider the case of a circuit in which the inductor, capacitor, and the resistance are connected in series across an AC source.

The condition for the series resonance is,

XL=XC

Here, XL is the inductive reactance and XC is the capacitive reactance.

The expression for the resonant frequency for a series RLC circuit is given by,

f=1 / 2π√LC

Thus, the resonance in a series circuit is explained. Want to know more about RLC circuits go through the concepts about RLC circuit in circuit theory of electrical engineering
