Professional Series Parallel Resonance FAQ Questions and Answers

Welcome to our comprehensive Trivia Quiz and interview preparation guide. Below you will find a curated list of popular Trivia Questions and Answers specifically for Series Parallel Resonance. Whether you are preparing for a technical interview or just testing your knowledge, these FAQ Questions will help you succeed.

What is meant by electrical resonance?

When impedance in the circuit is minimum current is maximum this is known as electrical resonance.

What is the condition for resonance?

XL = XC
Inductive reactance = capacitive reactance, Z becomes minimum, When Z = R.

What is the value of Z in LCR series circuit at resonance?

Z = R

What is the resonance frequency?

The frequency of applied AC at which resonance takes place or current is maximum.

Expression for resonance frequency?

fo = 1 / 2πsqrt(LC) , fo is independent of circuit resistance.

Define band width ?

In series LCR circuit, bandwidth is defined as the range of frequency for which the power dissipated in the resistance is equal to half the power dissipated at resonance.

In general, what is the expression for bandwidth ?

Bandwidth=(f2 - f1) in Hz

What are f1, f2 ?

f1, f2 are half power frequencies. The values of frequencies at which the power input is half its maximum value are called half power frequencies.

What are characteristics of series resonance?

a) Z is minimum when Z = R.
b) I is maximum, Im = V / Zmin = V / R
c) I is in phase with V i.e. φ = 0.
d) Reactance = 0, i.e. XL = XC.

Why do you call LCR series resonance circuit as an acceptor circuit?

It offers a low impedance to the current at a resonance frequency, it is called acceptor circuit
