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
- ALI^2
- B2LI^2
- C3LI^2
- D4LI^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 = 1 2 L_ eq I^2 . Substituting the value of L_ eq , we get U = 1 2 (4L) I^2 = 2LI^2 . Answer: 2LI^2
