How does the switch store energy

Does a capacitor store energy in a magnetic field?

Several chapters ago, we said that the primary purpose of a capacitor is to store energy in the electric field between the plates, so to follow our parallel course, the inductor must store energy in its magnetic field. We can calculate exactly how much is stored using tools we already have.

What happens when a switch is closed?

When the switch is closed, the current that points right-to-left for the inductor increases in the direction of the loop. As a result of Faraday's law, the inductor becomes a "smart battery" that acts to reduce the current, which means there is a voltage drop: Einductor = − LdI dt

Why is energy stored in a capacitor?

Eugene Sh. It might be more helpful to visualize the energy in a capacitor as being stored in the electric field between the plates. This electric field arises because of the displacement of the charge from one plate to the other. If it weren't for this field, it wouldn't have required any energy to shift the charges in the first place.

Do batteries store electrical energy?

There are no batteries that actually store electrical energy; all batteries store energy in some other form. Even within this restrictive definition, there are many possible chemical combinations that can store electrical energy--a list too long to go into in this short explanation.

How does voltage change over time?

As time progresses, the voltage across C decreases (as the charge flows out) and the rate of change of current necessary to maintain the inductor voltage at the same level as the capacitor voltage decreases. The current is still increasing, but its gradient is decreasing.

What chemical combinations can store electrical energy?

Even within this restrictive definition, there are many possible chemical combinations that can store electrical energy--a list too long to go into in this short explanation. There are two fundamental types of chemical storage batteries: the rechargeable, or secondary cell, and the non-rechargeable, or primary cell.
