Alternating Cur...

A resistor and a capacitor are connected in series with an ac source. If the potential drop across the capacitor is 5 V and that across resistor is 12 V, the applied voltage is

An alternating e.m.f. is applied to purely capacitive circuit. The phase relation between e.m.f. and current flowing in the circuit is or In a circuit containing capacitance only

The average power dissipated in a pure inductor of inductance L when an ac current is passing through it, is
(Inductance of the coil L and current I)

An alternating voltage is connected in series with a resistance R and an inductance L. If the potential drop across the resistance is 200V and across the inductance is 150 V, then the applied voltage is

In a circuit containing an inductance of zero resistance, the e.m.f. of the applied ac voltage leads the current by

In a pure inductive circuit or In an ac circuit containing inductance only, the current

A 20 volts ac is applied to a circuit consisting of a resistance and a coil with negligible resistance. If the voltage across the resistance is 12 V, the voltage across the coil is

For a series LCR circuit at resonance, the statement which is not true is

The power factor of LCR circuit at resonance is
