Equipotential Surfaces

Assertion: Two equipotential surfaces cannot cut each other.
Reason: Two equipotential surfaces are parallel to each other.

Assertion(A): Electric field is always normal to equipotential surfaces and along the direction of decreasing order of potential.

Reason (R): Negative gradient of electric potential is electric field.

The current following through a pure inductor of inductance $4 \mathrm{mH}$ is $i=12\cos 300t$ ampere. What is $rms$.

The instantaneous values of current and voltage in an circuit are given by $I=6\sin \left(100\mathrm{\pi t}+\frac{\mathrm{\pi }}{4}\right),V=5\sin \left(100\mathrm{\pi t}-\frac{\mathrm{\pi }}{4}\right)$. Then

In an ac circuit the current $B$ $i=5\sin \left(100t-\raisebox{1ex}{$\mathrm{\pi }$}\!\left/ \!\raisebox{-1ex}{$2$}\right.\right)$ $A$ and the A.C. potential is $V=200\sin \left(100t\right)$ Volt. Then the power consumed is.
