When current is maximum in RLC circuit?

If the circuit is a series RLC then the current is maximized at resonance but if it is a parallel RLC then the current is effectively zero at resonance. This can be understood intuitively by looking at the phase of the reactive components of the circuit.

Is current is maximum or minimum at resonance in a series RLC circuit?

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 the current maximum or minimum at the resonance?

So, in a series resonant circuit, voltage across resistor is equal to supply voltage i.e V = Vr. In series RLC circuit current, I = V / Z but at resonance current I = V / R, therefore the current at resonant frequency is maximum as at resonance in impedance of circuit is resistance only and is minimum.

Is current constant in an RLC circuit?

When a resistor, inductor and capacitor are connected in series with the voltage supply, the circuit so formed is called series RLC circuit. Since all these components are connected in series, the current in each element remains the same, Let VR be the voltage across resistor, R.

Why current is minimum in parallel resonance?

As the total susceptance is zero at the resonant frequency, the admittance is at its minimum and is equal to the conductance, G. 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.

Why does current oscillate in RLC circuit?

Once the capacitor is discharged, the inductor resists any change in the current flow, causing the capacitor to be charged again with the opposite polarity. The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction. The result is an oscillation, or resonance.
