Energy Stored in an Inductor

When the current in a practical inductor reaches its steady-state value of I m = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero.

6 FAQs about [Power storage inductor]

What is the rate of energy storage in a Magnetic Inductor?

Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.
