Alternating Current | AC Voltage Applied To A Series LCR Circuit

An alternating voltage is applied to a series L-C-R circiut. If the current leads the voltage by 45^(@) , then

Assertion (A) : At resonance , the current becomes minimum is a sreies LCR circuit. Reason (R) : At resonance, voltage and current are in same phase in a series LCR circuit.

An LCR circuit is connected to a source of alternating current. At resonance, the applied voltage and the current flowing through the circuit will have a phase difference of

Phase relationship between current (l) and applied voltage (E) for a series LCR circuit is shown here. omega_(0) = Resonant angular frequency of the circuit and omega = Applied angular frequency .

When an AC voltage, of variable frequency is applied to series L-C-R circuit , the current in the circuit is the same at 4 kHz and 9 kHz. The current in the circuit is maximum at

At resonant frequency the current amplitude in series LCR circuit is
