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 parallel-resonance-frequency-1. Whether you are preparing for a technical interview or just testing your knowledge, these FAQ Questions will help you succeed.

What is parallel resonance?

IL and IC are such that the resultant current I is in phase with the supply voltage, then the network is said to be in resonance.

What is the current at resonance?

Current is minimum because impedance is maximum.

What is the meant by rejector circuit?

As the parallel resonate circuit offers high impedance to the current at the frequency, the circuit is called a rejector circuit.

What is a tank circuit?

A parallel resonate circuit is called tank circuit. This produces oscillations in the network.

What is anti-resonance?

The condition of parallel resonance is called anti-resonance.

What is resonance curve?

A variation of line current with frequency is called resonance curve.

What are the characteristics of parallel resonance?

The main characteristics of parallel resonance are:
1. The circuit impedance is maximum
2. The circuit current is minimum
3. I is out of phase with V.

What is impedance?

Combined effect of reactance and resistance Z = Vrms / Irms

Expression for resonance frequency?

Resonant frequency is given by fo = 1 / 2πsqrt(LC)

Define self-inductance of a coil?

It is the property of the coil due to which it opposes the change of current in the circuit.

What do you mean by Quality factor(Q-factor)?

The ability of a reactive device to store energy as compared to the dissipation of the energy within the device is called Q-factor. It is given by Q = XL / R = fo / (f2 - f1)
