To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
A split-phase motor uses a centrifugal switch to energize and de-energize the start winding. The switch is connected in series with the start winding circuit and is typically set to open when the motor reaches about 75-80% of its operating speed, disconnecting the start winding from the power supply.
That is described as a circuit in series, as opposed to a circuit in parallel, in which there is more than one loop.
When one electrical circuit controls another circuit through a relay, the first circuit is called the "control circuit." The control circuit operates the relay, which in turn switches the second circuit, known as the "load circuit," on or off. This allows for the control of high-power devices using a low-power signal.
Generally a circuit breaker (like a light switch) But I guess you could use a resistor of the right resistance If you are talking about the circuit breaker there is an electromagnetic coil in it which get magnetized on a specific amount of current and breaks the circuit
In a lighting circuit an open circuit will turn off the light.
A ground fault circuit interrupter is the device used to de-energize the circuit.
Ground Fault Circuit Interrupter (GFCI).
This depends on your service voltage and whether you have any step down transformers in the building. The only way to know is to check yourself. Use a voltmeter or multimeter, with one lead on L1 terminal and one lead on Neutral terminal. Set the meter to read AC volts, with a range of at least 300 volts (your reading should either be 277 or 120.) The safest way to do this is to deenergize the circuit, place your leads, and then re-energize the circuit without touching anything. You should be able to get a reading without touching anything at all.
Because circuit is a circuit.

An open circuit or a short-circuit (if that circuit is complete).
A parallel circuit is :)
A series circuit is actually in series, but a parallel circuit, is Parallel
The circuit breaker for the headlights is intergrated with the headlight switch.
I guess Electric Circuit....
The circuit is considered a closed circuit.
A lighting circuit would be a parallel circuit.
