Application +4 | -1

An LR circuit has

L=1 \mathrm{~H}

and

R=1 \Omega

. It is connected across an emf of

2 \mathrm{~V}

. The maximum rate at which energy is stored in the magnetic field is:

View answer and explanation

Correct option: A

1 \mathrm{~W}

Option A (1 W) is correct because the maximum rate at which energy is stored in the magnetic field is equal to 1/2 * L * I², where I is the maximum current.

Assertion (A) : In an

\mathrm{AC}

circuit, potential difference across the capacitor may be greater than the applied voltage.

Reason (R) :

V_C=I X_C

, whereas
