Speed of electronsYou can indeed calculate this if you have much more information. (See the nearby link.)

But the surprising thing is that the electrons travel VERY SLOWLY. In fact, if the electrons had to get to the lamp before you would see the light, we would wait several seconds in the dark each time we turned on the light.

So the energy transfer in a circuit is wildly different from the electron transfer.

### What is close circuit and an open circuit?

a closed circuit is a complete circuit with no breaks at all, one example:- a closed circuit occurs when you turn the light switch on an open circuit has a physical break in the circuit, which stops the flow of electrons. one example is when the lights are turned off, the switch creates a physical break in the circuit

### What happened when you turned on the switch of the light?

A switch is placed in an electrical circuit in order to place a gap when the switch is off, so the circuit is broken. When the switch is on, the circuit is complete and the electricity can flow round the circuit.

a closed circuit

### When a switch in an electrical circuit is turned off what will happen?

Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.

### When a light switch is turned on what is done to the curcuit?

When a light switched is turned on the circuit is usually closed.

### When the switch is closed it means that?

There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.

### Can a switch in the off position cause electrical short circuit?

No, once the switch is turned off the circuit is de energized. A de energized circuit can not be shorted out to create a fault.

### How does a circuit turn a switch on and off?

A switch makes a physical break in the electric circuit. With the circuit broken the electricity can not flow. When the switch is turned the other way the circuit is completed and the current/electricity can flow.

### Why do the electrical gadgets stop working when switch is turned off?

A switch breaks the flow of electrons (current).
