An inductor used in a dc power supply has an inductance of 11.0 H and a resistance of 130 Ω. It carries a current of 0.550 A. What is the energy stored in the magnetic field? At what rate is thermal energy developed in the inductor?

Part A

What is the energy stored in the magnetic field?

Part B

At what rate is thermal energy developed in the inductor?

Expert Solution

Part A) energy stored in the magnetic field = 1/2 * L * I²

= 1/2 * 11.0 * 0.550²

= 1.66375 J

Part B) rate is thermal energy developed in the inductor = I² R

= 0.550² * 130

= 39.325 W
