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.

What is a line commutation?
it is the natural commutation ...by making open circuit or short circuit on the thyristor to make it turn off.
What must you always do before taking apart a circuit?
Turn off the power!
If one bulb fails and all the others turn off you are dealing with a?
A circuit of a series configuration.
Why bulb does not work when fitted in a circuit with switch?
because you are switch the hot leg, so it can be turn on an off.
Is there a switch available to control power to a thermostat for 20A 240V electric baseboard heater?
There are two types of thermostats. One is a line voltage stat. This is in effect a switch and when turned to the off position the voltage is interrupted and the heater will not operate. The other type of stat is low voltage. There will be a relay in the baseboard heater that the thermostat is connected to. With this type if installation to turn the power completely off you will have to turn the breaker off that feeds the circuit.
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.

What happens to a circuit when you turn off a flashlight?
The circuit will stop working once turn off a flashlight.
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 does the on and off switch do on an electrical circuit?
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
What is a circuit in which electricity doesn't flow called?
In a lighting circuit an open circuit will turn off the light.
When you turn off a lighbulb do you closing or opening a circuit?
opening of circuit..
What is the function of electric circuit control device?
the function of the control device is that you can know if the circuit is on or off
What happens if you turn off the electric current in the solenoid?
If you turn off the electric current in the solenoid, the solenoid quits pulling its armature.
What two jobs does a lever do?
A lever is used to turn on a circuit A lever is also used to turn off a circuit
Why a switch might be added to a circuit?
So you can turn it on... and you can turn it off...!
