If the capacitance of a pure capacitor in a $DC$ circuit is $1 \ F$,then what will be its capacitive reactance?

The same current is flowing in two alternating circuits. The first circuit contains only an inductor and the other contains only a capacitor. If the frequency of the alternating e.m.f. is increased,the values of current will

The average power dissipation in a pure capacitance in an $AC$ circuit is

Same current is flowing in two different $A.C.$ circuits. The first circuit contains only an inductance $(L)$ and the second contains only a capacitance $(C)$. If the frequency of the $A.C.$ source is increased in both circuits, what will happen to the current?

$A$ $0.7\,H$ inductor is connected across a $120\,V, 60\,Hz$ $AC$ source. The current in the inductor will be very nearly: (in $,A$)

Explain the representation of $AC$ current and voltage by rotating vectors.
