In which conditions does resonance occur?

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. At low frequencies the series circuit is capacitive as: XC > XL, this gives the circuit a leading power factor.

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

Concept: In series LCR circuits, Resonance is a condition in which the inductive reactance and capacitive reactance are equal and lie opposite in phase, so cancel out each other. Only, resistance is left as impedance. At resonance, the impedance of the series LCR circuit is minimum and hence the current is maximum.

What is the condition for resonance in RLC parallel circuit?

Resonance occurs in a parallel RLC circuit when the total circuit current is “in-phase” with the supply voltage as the two reactive components cancel each other out. At resonance the admittance of the circuit is at its minimum and is equal to the conductance of the circuit.

Is the condition for resources in RLC series circuit?

Hi, When the circuit allows maximum current for a given frequency of the source of alternating supply for which capacitive reactance becomes equal to the inductive reactance . The impedance of LCR Circuit is minimum and hence current is maximum.

Which criteria satisfies Overdamped condition in RLC circuits Mcq?

A circuit will be overdamped if the resistance is high relative to the resonant frequency.

What causes resonance frequency?

Resonance only occurs when the first object is vibrating at the natural frequency of the second object. As we have learned earlier, an increase in the length of a vibrational system (here, the air in the tube) increases the wavelength and decreases the natural frequency of that system.

What conditions in series produce resonance and parallel resonance?

1. Series resonance occurs when the impedance to current flow at a certain frequency (or frequencies) is low. 2. Parallel resonance occurs when the impedance to current flow at a certain frequency (or frequencies) is high.

What are the conditions of series and parallel resonance?

The main difference between series and parallel resonance is that series resonance occurs when the arrangement of the components creates the minimum impedance, whereas parallel resonance occurs when the arrangement of components creates the largest impedance.

What is resonance derive the condition for maximum resonance?

Resonance of an RLC circuit refers to the condition when the voltage across the inductor is the same as the voltage across the capacitor, or V L = V C { V }_{ L } = { V }_{ C} VL​=VC​. As a result, the EMF of the battery is entirely consumed by the resistor and the current achieves its maximum value.

What is resonance in a series RLC circuit?

The resonance of a series RLC 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 resonance condition in a parallel circuit?

Similar to the series circuits, when resonance occurs in a parallel RLC circuit the resonance condition (Equation 1) leads to other relationships or properties: Current in the inductor is equal to the current in the capacitor. Current in the resistor is equal to the total circuit current.

What is the difference between voltage resonance and series resonance?

Since in this resonance the voltage is maximum, it is called the voltage resonance. The series resonance is also called an acceptor circuit because such a circuit accepts currents at one particular frequency but rejects currents of other frequencies.

How do the reactances cancel each other out at resonance?

We can see then that at resonance, mathematically the two reactances cancel each other out as X L – X C = 0. This makes the series LC combination act as a short circuit with the only opposition to current flow in a series resonance circuit being the resistance, R.
