When you turn It off it breaks the circuit. When it is turned on it closes the circuit. To have a light bulb turn on it need to have continuity. Hope that helps

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.
It closes the electrical circuit.?
The definition of a switch is a device that closes and opens an electrical circuit.
What does a push switch do in a circuit?
it starts a circuit by connecting the circuit and the initials are ptm and its a spdt switch
How do you de energize an electrical circit?
De energising means you are disconnecting a device from electricty source. Switch off the device, physically disconnect the device to de energise the circuit.
What are switches used for in a circuit?
A switch is a means of making (on) or breaking (off) an electrical 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.
What happens to an electric current at a light switch?
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
What are you doing to the electrical circuit in your radio when you turn the radio off and on?
When you turn your radio on and off, you are simply flicking the switch in the circuit, the same as any circuit with a switch in it. When you turn it on, the switch completes the circuit, and current can flow around 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.
The functions of switch?
A switch turns on or off electrical power flowing through a cable or circuit.
How are electrical current and circuits related?
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
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.
What is happening when you turn an electric circuit off?
When you switch off an electrical circuit you tend to create a 'break' in the circuit, preventing the electric current to flow around the circuit, this can be caused by a simple switch or a break in the circuit, e.g a disconnected wire.
How does an electric switch help in an electric circuit?
A switch is a means of making (on) or breaking (off) an electrical circuit.
How does a lightswitch work?
A light switch fills(on) or makes (off) a gap in an electrical circuit.
