The voltage across a pure inductor is represented by the following diagram. Which of the following diagrams will represent the current?

$A$ capacitor of $50 \mu F$ is connected to a power source $V = 220 \sin 50 t$ (where $V$ is in volts and $t$ is in seconds). The value of the rms current (in amperes) is:

An alternating voltage source $V = 260 \sin(628t)$ is connected across a pure inductor of $5\,mH$. Inductive reactance in the circuit is $......... \Omega$.

$A$ parallel plate capacitor having plates of radius $6 \text{ cm}$ has capacitance $100 \text{ pF}$. It is connected to a $230 \text{ V}$ a.c. supply with angular frequency $300 \text{ rad/s}$. The r.m.s. value of current is:

An alternating $e.m.f.$ of angular frequency $\omega$ is applied across an inductance. The instantaneous power developed in the circuit has an angular frequency
