The current and $EMF$ through an inductance differ in phase by

$A$ resistor of resistance $100 \Omega$ is connected to an $AC$ source $\varepsilon = 10 \sin (250 \pi t)$. The energy dissipated as heat during $t = 0$ to $t = 1 \text{ ms}$ is approximately.

An alternating voltage $e = 150\sqrt{2} \sin 100t \text{ V}$ is applied to a capacitor of capacity $2 \mu F$. The root mean square value of current in the circuit is (in $mA$)

Explain $AC$ voltage applied to a resistor and explain it with a necessary graph.

In a purely resistive $ac$ circuit,the current

When a pure resistor is connected to an $AC$ source,the phase difference between the voltage and the current through the resistor is (in $^{\circ}$)
