# An RLC series circuit remains predominantly inductive

An RLC series circuit remains predominantly inductive

### Right Answer is: Above resonance frequency

#### SOLUTION

An RLC series circuit remains predominantly inductive at resonance frequency.

## RLC Series Circuit

Inductive reactance(XL) = 2πf L

Capacitive reactance(XC) = 1/(2π f c)

• Capacitance: At frequencies below the resonance i.e fr, Xc > XL the current leads the source voltage and the circuit is totally capacitive. The phase angle decrease as the frequency reaches 0 degrees.
• Inductive: At frequencies above the resonance i.e fr, XL > Xc the current lags the source voltage and the circuit is totally inductive. The phase angle increases as the frequency approach 180 degrees.
