How is energy stored in an inductor?

The energy in an inductor is stored in the magnetic field which is generated by the current passing through the inductor. In terms of how the energy gets there you need to think of the inductor having no current passing through it at the start and then applying a voltage source across the inductor.

Why is a pure inductor not present?

This results in the flow of current. it can be said that the, energy stored in the the inductor is due to the temporary alignment of these dipoles. but few magnetic dipoles can not attain their initial configuration. hence, we say pure inductor is not present practically. Scientists know that the electric fields and magnetic fields are co-related.

How do inductors work?

This principle finds practical use in devices such as transformers, which transfer energy between circuits, and in electrical grids, where inductors help manage the flow of electricity, maintaining stability and preventing surges.

What is a 1 h inductor?

A 1 H inductor is a large inductor. To illustrate this, consider a device with L = 1.0H L = 1.0 H that has a 10 A current flowing through it. What happens if we try to shut off the current rapidly, perhaps in only 1.0 ms? An emf, given by emf = −L(ΔI/Δt) e m f = − L (Δ I / Δ t), will oppose the change.

How do you find the instantaneous power in a pure inductor?

Considering a pure inductor L, the instantaneous power which must be supplied to initiate the current in the inductor is P = i v = L i d i d t The work done by the voltage source during a time interval d t is d W = P d t = i L d i d t d t = L i d i

How does an inductor respond to a sudden change?

If the current changes dramatically and suddenly, then the inductor will respond by providing an emf that opposes the sudden change, reducing the amount that the current is able to change over a short period, protecting the system from potential damage.
