What is the current resonance?
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. The high value of current at resonance produces very high values of voltage across the inductor and capacitor.
What is meant by resonance of a circuit?
The response of the circuit to signals of different frequencies is a function of the inductance and capacitance of the circuit and peaks at one frequency value, at which the current flow resonates most strongly with the input signal. …
Is current maximum in resonance?
In series RLC circuit at resonance impedance is minimum hence current is maximum but in parallel RLC circuit at resonance admittance is minimum which means impedance is maximum hence current is minimum.
Is current minimum at resonance?
Therefore at resonance the current flowing through the circuit must also be at its minimum as the inductive and capacitive branch currents are equal ( IL = IC ) and are 180o out of phase. At resonance, currents IL and IC are equal and cancelling giving a net reactive current equal to zero.
What is the bandwidth of the circuit?
Question: What is the bandwidth of the circuit OR What do you mean by bandwidth of circuit? Answer: Bandwidth or BW of the resonant circuit is defined as the difference between the frequencies at which the circuit delivers half of the maximum power.
What is resonance in series 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 resonant current?
This condition is called resonance. The value of the frequency at which this happens is called resonant frequency. In this case the current starts oscillating between the inductor and the capacitor. The current at resonant frequency is called the resonant current.
What is an example of resonance in a circuit?
For example, electrical resonance occurs in a circuit with capacitors and inductors because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor.
What is the resonance frequency of a capacitor?
The value of the frequency at which this happens is called resonant frequency. In this case the current starts oscillating between the inductor and the capacitor. The current at resonant frequency is called the resonant current. The mathematical condition for this is. This gives resonant frequency.
What is mechanical resonance and how does it work?
Mechanical resonance can be defined as the tendency of a mechanical system to respond at greater amplitude when the frequency of its oscillations matches the system’s natural frequency of vibration (its resonance frequency or resonant frequency) than it does at other frequencies.
