Time when the switch electrical equipment is not storing energy

Is electricity wasted when a switch is on?

Therefore electricity is not wasted. The above case is when the switch is ON and the plug is not inserted into the socket (notice in the circuit, there is no connection between plug and socket). Now we shall take the case when the switch is ON and the plug is connected but the device also has a switch, lets say Sd, which is turned OFF.

Can a power switch run without a circuit plugged in?

No. With nothing plugged in there is no circuit, so no current can flow. An exception to this is if the socket or the switch has an indicator light - usually a neon one - that is illuminated when the switch is on. In that case the light will use a (very small) amount of power.

What happens if a switch is on and not connected?

The switch is “ON” and the plug is inserted into the socket (Ls-Lp and Ns-Np are shorted). The current takes the path as shown (Blue colour lines), the device/appliance is powered and electricity is consumed. Now if the switch is ON and we have not connected any device to the socket i.e we are not using it.

Where does energy storage take place in an electric circuit?

In double-energy electric circuits, energy storage takes place in the magnetic field of inductors and in the electric field of the capacitors. In real circuits, the interchange of these two forms of energy may, under certain conditions, produce electric oscillations.

What happens if a switch is not inserted into a socket?

It is an open circuit even when the switch is ON. There is no current/electricity in the circuit. Therefore electricity is not wasted. The above case is when the switch is ON and the plug is not inserted into the socket (notice in the circuit, there is no connection between plug and socket).

What happens if a switch is not plugged into a power point?

With nothing plugged into the power point, there is no closed circuit, i.e. no connection, so no current flow. Simple electrical theory...switch off, no closed circuit, thus no power flow. Unless, of course, there is a light of some kind which illuminates when the switch is turned on. The light will consume a minimal amount of power.
