Reason why the switch does not store energy

What happens if a switch is not handled properly?

These events are called quenches, and they can do permanent damage if not handled properly. Even better, because the switch cannot throw infinitely fast, there will be finite lengths of time during which one contact is arbitrarily close to the other, so the voltage gradient arbitrarily high.

What happens if electrical energy is stored in a house?

The more electrical energy is stored, the greater the possibility of breakdown of insulation. It is as if one built a dam and the water could easily find a hole on the floor or break the dam.

Can a short circuit dissipate power?

(And before you say "through the short circuit", I remind you that a short circuit has no resistance, and therefore cannot dissipate power) Suppose an inductor is connected to a source and then the source is disconnected. The inductor will have energy stored in the form of magnetic field. But there is no way/path to discharge this energy?

Is a switch a complete circuit or a closed circuit?

The switch is closed and there is a complete circuit. Will not glow. There is a closed circuit but the two negative terminals of the cells are connected, rather than a negative connected to a positive terminal. Will glow. There is a complete circuit with an energy source. Will not glow. There is a complete circuit but no energy source.

What if a switch is in a perfect vacuum?

You probably mean the switch, not the coil, is in a perfect vacuum. A fine example of the stored energy of an inductor used to generate a useful voltage, is the ignition coil in petrol engines.

What happens if LC oscillations are lost in a battery?

In the former case, half of the energy supplied by the battery is lost to heat in the circuit. In the latter case, the LC oscillations are eventually damped by a combination of ordinary resistance and radiation resistance, i.e. half of the energy goes into heat or electromagnetic waves.
