Energy storage motor is not storing energy switch is disconnected

Can a device store energy if L is a constant?

If L is a constant (which is often dt dt dt true) then v = L di which means vdt = Ldi, which we can substitute dt into the equation for Energy above yielding: which in all likelihood you will have seen before in a physics class. In both of these cases, the device can store energy and therefore its source-like constitutive relation makes some sense.

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.

Why does a coil store no energy?

This is not an equilibrium configuration and then, since the electrons in the metal are free to move, the charges redistribute in the wire, nullifying the potential difference. Now the coil stores no energy. So where did the energy go?

Where should Enphase Energy System (EES) disconnecting devices be mounted?

NOTE: Enphase Energy System (EES) disconnecting means may need to be mounted in a readily accessible location, within sight of equipment or outside. NOTE: To meet additional requirements of the NEC, the rapid shutdown device may need to be mounted in a readily accessible location or outside.

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 when a switch reaches a 1000 Volt voltage?

Well, almost. When the voltage across the opening switch reaches several 1000 volts, the air between the contacts of the switch gets ionized and becomes an electrical conductor. According to "Electrical breakdown - Gases" air begins to break down at 3000 V/mm. You will actually see and hear a spark in the switch.
