$A$ $120 \, V$ $AC$ source is connected across a pure inductor of inductance $0.70 \, H$. If the frequency of the source is $60 \, Hz$,the current passing through the inductor is: (in $, A$)

An alternating e.m.f. is applied to a purely capacitive circuit. What is the phase relation between the e.m.f. and the current flowing in the circuit?

In a circuit,the current lags behind the voltage by a phase difference of $\pi / 2$. The circuit will contain which of the following?

In the graphical representation of e.m.f. $e$ and current $i$ versus $\omega t$ for an a.c. circuit,both emf and current reach zero,minimum,and maximum values at the same time. The circuit element connected to the source will be

An alternating voltage $v = 200 \sqrt{2} \sin(100 t)$ is connected to a $1 \mu F$ capacitor through an $A.C.$ ammeter. The reading of the ammeter shall be: (in $\text{ mA}$)

The reactance of a capacitor of capacitance $C \mu F$ for an $ac$ frequency of $\frac{400}{\pi} \ Hz$ is $25 \ \Omega$. The value of $C$ is ..... $\mu F$.
