What happens to the impedance of RLC parallel circuit at resonance?

Also at resonance the parallel LC tank circuit acts like an open circuit with the circuit current being determined by the resistor, R only. So the total impedance of a parallel resonance circuit at resonance becomes just the value of the resistance in the circuit and Z = R as shown.

Why the coil with large distributed capacitance has a high resonant frequency?

A coil with large distributed capacitance has “high resonant frequency” . Explanation: It is the highest frequency for which the coil is inductive and thus establishes an upper limit on the frequency for which the coil can provide inductive reactance.

How does the resonance frequency of an RLC series circuit?

Resonant Frequency in a Series RLC Circuit At its resonant frequency, the total impedance of a series RLC circuit is at its minimum. It also means that the current will peak at the resonant frequency as both inductor and capacitor appear as a short circuit. Frequency response of a series RLC circuit.

What happen to the output if the frequency of the sources is increase?

If the frequency is increased the op amp will be even less able to keep up and therefore the amplitude of the output waveform will decrease.

What is the RLC frequency of a circuit?

The value of RLC frequency is determined by the inductance and capacitance of the circuit. Resonance occurs in series as well as in parallel circuits. Although the basic formula to calculate series and the resonant frequency is same, However, there are certain differences which governs the resonant frequency.

What is the meaning of RLC resonance?

RLC Resonance is a special frequency at which the electrical circuit resonates. The value of RLC frequency is determined by the inductance and capacitance of the circuit. Resonance occurs in series as well as in parallel circuits.

Why current is maximum at the resonant frequency in Series circuit?

It is clear from the above discussion that the current is a series RLC resonance circuit is maximum at the resonant frequency and it decreases on either side of this frequency. Thus this circuit has a property of selecting signals of one particular frequency.

Why is the graph of capacitive reactance against frequency hyperbolic?

The graph of capacitive reactance against frequency is a hyperbolic curve. The Reactance value of a capacitor has a very high value at low frequencies but quickly decreases as the frequency across it increases. Therefore, capacitive reactance is negative and is inversely proportional to frequency (XC ∝ ƒ -1)
