An inductive circuit contains a resistance of $10 \,ohm$ and an inductance of $2.0\, henry$. If an ac voltage of $120 \,volt$ and frequency of $60\, Hz$ is applied to this circuit, the current in the circuit would be nearly……$amp$

An inductor $(L = 100\ mH)$, a resistor $(R = 100 \Omega)$ and a battery $(E = 100\ V)$ are initially connected in series as shown in the figure. After a long time the battery is disconnected after short circuiting the points $A $ and $ B$. The current in the circuit $1\ ms$ after the short circuit is

An ac-circuit having supply voltage $E$ consists of a resistor of resistance $3\Omega$ and an inductor of reactance $4\Omega$ as shown in the figure. The voltage across the inductor at $t = \pi /\omega$ is…….$volts$

Figure shows a circuit that contains four identical resistors with resistance $R =2.0\, \Omega,$ two identical inductors with inductance $L =2.0 \,mH$ and an ideal battery with $e m f E =9 \,V .$ The current $'i'$ just after the switch $'S'$ is closed will be …. $A$

An alternating $emf$ $E =440 \sin 100 \pi t$ is applited to a circuit containing an inductance of $\frac{\sqrt{2}}{\pi} H$. If an a.c. ammeter is connected in the circuit, its reading will be $…….A$
