Question:

if a 3.0 current passes through an inductor?

A 3.0A current passes through an inductor. If the inductor stores 19 J of energy, what is the inductance?A) 3.6 HB) 4.22 HC) 85.5 HD) 57 H

Answer:

The energy stored is E(1/2)LI^2 where E: energy L: inductance I: current so L2E/I^2 L2*19/3^2 L4.22 H
