Alternating current through an inductor lags behind the alternating voltage by `90^(@)`. What does it imply ?

What is meant by alternating voltage?

The current through an inductor of impedance 10Omega lags behind the voltage by a phase of 60^(@) when just the inductor is connected to the ac source. Now the inductor is connected to a 5Omega resistance in series, then the net impedance of the circuit is

What will be the peak value of the alternating current when a condenser of 1muF is connected to an alternating voltage of 200V, 60 Hz?

If an alternating current i = i_(m )sinomegat is flowing through an inductor then voltage drop DeltaV_(L) across inductor L will be-

In a series LCR circuit R= 200(Omega) and the voltage and the frequency of the main supply is 220V and 50 Hz respectively. On taking out the capacitance from the circuit the current lags behind the voltage by 30(@) . On taking out the inductor from the circuit the current leads the voltage by 30(@) . The power dissipated in the LCR circuit is
