Important Questions on Alternating Current
In the shown circuit phase different between currents and is



A periodic voltage wave from has been shown in fig. Determine the average value of voltage (in ).

The source voltage and current in the circuit are represented by the following equations .
Find Impedance of circuit (in ohm).

When an alternating voltage of is applied across a device , a current of flows through the circuit and is phase with the applied voltage. When the same voltage is applied across another device , the same current again flows through the circuit but it leads the applied voltage by radians.
Calculate the current (in ampere) flowing in the circuit when same voltage is applied across the series combination of and .


An alternating voltage with angular frequency is connected across the capacitor and inductor having and . Find the ratio of current through inductor to source.
