A switch is used to connect or disconnect a load from a source of voltage. If you take the input and connect directly to the output the result is that the connected device is always on.
The switch would be open.
A switch allows the circuit to have a break in it therefor making it not work. It stops the flow of electrons.
Not always. Depends on the circuit.
Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
If an appliance does not work at all when you plug it in and turn the switch on the appliance circuit is not on.
The appliance's circuit is open.
No. Since the switch is in series with the circuit, opening it blocks the current flow through the circuit, turning it off.
Either close the circuit, or complete the circuit, should work here.
Current flow path is open.
because you are switch the hot leg, so it can be turn on an off.
There's continuous power supplied to the circuit. When the switch contacts, it closes the circuit and allows the power to go to the brake lights.
Basically, when you click that switch, it completes a circuit for the electricity to flow. If the circuit is not completed in any part, the circuit will not work at all
