When four inductors of the same inductances L are connected in series, and I is the current passing through the circuit. The energy stored in the circuit is

Options

A $LI^2$
B $2LI^2$
C $3LI^2$
D $4LI^2$

Correct answer

B. $2LI^2$

Step-by-step solution

The equivalent inductance of four inductors connected in series is given by

L_{eq} = L + L + L + L = 4L

.

The energy stored in the circuit is given by

U = \dfrac{1}{2} L_{eq} I^2

.

Substituting the value of

L_{eq}

, we get

U = \dfrac{1}{2} (4L) I^2 = 2LI^2

.

Answer:

2LI^2
