An RL circuit has L = 0.40 H and R = 5.0 Ω.It is connected to a battery with ε = 22 V at time t = 0.Find the energy stored in the inductor when the current in the circuit is 2.3 A.
A) 5.0 J
B) 2.0 J
C) 50 mJ
D) 1.1 J

The energy stored in an inductor is given by the formula:

E = 1/2 * L * I^2

Where E is energy stored, L is inductance, and I is current.

Plugging in the given values, we get:

E = 1/2 * 0.40 H * (2.3 A)^2 = 1.1 J

Therefore, the correct answer is D) 1.1 J.
