$A$ sinusoidal supply of frequency $10 \,Hz$ and $r.m.s.$ voltage $12 \,V$ is connected to a $2.1 \,\mu F$ capacitor. What is the $r.m.s.$ value of current in $mA$?

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?

The graphs given below depict the dependence of two reactive impedances $X_1$ and $X_2$ on the frequency of the alternating e.m.f. applied individually to them. We can then say that

The current flowing in a coil is $3 \text{ A}$ and the power consumed is $108 \text{ W}$. If the a.c. source is of $120 \text{ V}, 50 \text{ Hz}$,the resistance in the circuit is (in $\Omega$)

An $a.c.$ of frequency $f$ is flowing in a circuit containing only an ideal choke coil of inductance $L$. If $V_0$ and $i_0$ represent peak values of the voltage and the current respectively,the average power given by the source to the choke coil is equal to

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 $I$)
