What is the condition of resonance in an LCR circuit?

The resonance of a series LCR circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase.

What is the impedance in LCR circuit?

What is the Impedance of LCR Circuit? In electrical engineering, impedance is the measure of the resistance that a circuit exerts to current with the application of voltage. Impedance can be minimized by making the applied AC frequency equal to the resonant frequency of the LCR circuit.

What is condition for resonance?

The conditions to produce resonance in an object are: The object must have a minimum of one natural frequency of vibration. The object must be driven by an external force of vibration. The frequency of the external vibrating force must be similar to the object’s natural frequency of vibration.

What is the condition for resonance in RLC series circuit formula?

Resonance occurs when XL = XC and the imaginary part of the transfer function is zero. At resonance the impedance of the circuit is equal to the resistance value as Z = R.

What is the impedance at resonance condition?

Resonance is the result of oscillations in a circuit as stored energy is passed from the inductor to the capacitor. Resonance occurs when XL = XC and the imaginary part of the transfer function is zero. At resonance, the impedance of the circuit is equal to the resistance value as Z = R.

What is the condition for resonance in RLC series circuit Mcq?

Resonance occurs when XL = XC and the imaginary part of the transfer function is zero. At resonance, the impedance of the circuit is equal to the resistance value as Z = R.

How do you find the resonance frequency of a LCR circuit?

The resonant frequency is found by using the expression in f0=12π√LC f 0 = 1 2 π L C . The current at that frequency is the same as if the resistor alone were in the circuit.
