What is minimum impedance circuit?

The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance. This would occur at a frequency above the resonant frequency.

What are the conditions for series resonance?

In RLC series circuit, when the circuit current is in phase with the voltage, the circuit is said to be in Series Resonance. The resonance condition in the circuit arises when the inductive reactance is equal to the capacitive reactance.

How does the total impedance of a series LCR circuit change?

As frequency of the applied ac signal increase, ​ ω L increases and 1 / ω C decreases. Therefore, total impedance increases.

Which of the following Cannot increase impedance in a series LCR circuit?

Increasing the voltage of the source. Impedance has no direct dependence on voltage. Therefore, impedance cannot be increased by increasing the voltage of the source.

When dose a series L-C-R circuit have the minimum impedance?

When dose a series L-C-R circuit have the minimum impedance? When the resistance is equal to zero. When the impedance is equal to zero. When the electric current is equal to zero. When the imaginary part of the impedance is equal to zero. When the resistance is equal to zero.

What is the minimum and maximum value of impedance?

Since impedance has Resistance in series with reactances of L and C, its minimum value is when reactance is zero. This happens when capacitive and inductive reactances cancel each other at resonance frequency. Maximum value occurs when either of the reactances is maximum (when one is maximum, the other is zero).

What is the condition for resonance in RLC circuit?

The condition for resonance is the inductive reactance and capacitive reactance both should be equal that is , At resonance,the impedance offered by the RLC circuit will be the resistance only ,capacitive reactance and inductive reactance won’t added up to impedance because,

What is the reactance of an LCR circuit?

In an LCR circuit, the inductive and capacitive reactance depend on the frequency of source supply. If it is zero, the then the reactive component is zero in the impedance and the circuit only has resistance. There is another case where this possible.
