That is the job done by a switch. When the switch is 'on' the two contacts in the switch are touching, which allows current to flow. When the switch is 'off' the contacts are not touching and no current can flow.
In small switches the power to alter the contacts comes from the user's finger.
A switch never absorbs power, because there is always either no current passing through it, or no voltage across it. That makes electronic switches very useful in circuits.

Which of these is an example of static electricity?
They stop the flow of electrons
An object that stops the flow of electricity is called?
An object that will stop the flow of a current is called a switch.
What device used to stop and start the flow of electricity in a circuit is a?
A switch is a device that stops and starts current flow in a circuit.
Why do people want switches on mechanisms that use electricity?
To control the flow of current - either to make it flow through the circuit or stop the flow through the circuit
When does electricity flow?
When there is a closed circuit, there is electricity flow.
Is voltage a flow of electricity?
no...current is a flow of electricity
How is the flow electricity of electricity mearsure?
flow of electricity is measured by an instrument galvanometer
Will a circuit work without a switch?
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
What stops the flow of electricity?
Turn off the switch, generator runs out of fuel, wind not turning the windmill, solar panel at night, diode, insulation.
Does an insulator allow electricity to pass through it easily?
NO!!! The whole point of an insulator is to stop electric flow.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
How does an insulator affect the flow of electricity?
It prevents the flow of electricity since they do not have mobile electrons or mobile ions to allow the flow of electricity.
