Sounds like a relay to me.

Why is an ammeter is always connected in series with the circuit?
When considering electricity, Current (measured in Amps) is often considered the flow of energy. The force behind the flow is the Volts. While the volts can be measured between any two points in the circuit (open, or closed), measuring the current, or flow of energy typically requires interrupting the flow. Somewhat like water. One can measure pressure of the water on a branch, but one must have a way to monitor the actual flow to determine how much water has passed. There are "exceptions" though. If you have an AC circuit, then an inductive ammeter can measure the amps around a single leg if the circuit without being installed inline with the circuit. Even with a DC circuit, it may be desirable to design a bypass or shunt circuit so that the majority of the current bypasses the ammeter, and only a small amount of the current actually flows through the ammeter.
How does High and Low voltage cut out circuit works if voltage varies?
I assume you mean - 'Why does a circuit fail to work if the operating voltage is too high or too low?' A certain specific voltage is needed to overcome the natural resistance in circuit components. For instance in simple transistors, this is 0.7V to get the transistor to switch on and 1.4V is lost across the switched junction. This is why may circuits operate at above 3V. The rest of the circuit is designed to operate at the specified voltage and if you go too high, too much current will flow through the circuit and it will fail in the same way a fuse will blow if too much current is passed through it.
When a current is passed through a coil of wire what forms Is it A. an electromagnet or B. A commutator?
a magnetic field
How much electrical current is passed through an ammeter in a time of 6 seconds if the ammeter reads 1.8 amps?
1.8 amps of current passed through. I'm assuming you meant electrical charge however, in which case 1.8 A * 6 s = 10.8 C of charge passed through, where C stands for Coulombs. That is equivalent to roughly 6.74 X 1019 electrons passing through.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
Why is quartz good for working watches and other electronic machines?
Quartz is a piezoelectric material. This means that it vibrates when current is passed through it. It also means that when it is vibrated or put under pressure, it generates current. When current is passed through a quartz element, it vibrates, which in turn puts some current back into the circuit. This creates a feedback look that creates a waveform in the electrical signal; this wave can then be used as a clock by using electronic components to measure the number of wave cycles that have passed. This means that quartz is an integral part of any timing circuit, and timing is important for watches, computers, and anything that requires coordination between different parts.
What is the use of resistor in the circuit?
A resistor develops a voltage differential when current is passed through it. Ohm's law: Voltage is current times resistance.
What is magnetization current?
There is no magnetic current because there are no magnetic charges.
Simple definition of electronic signal?
The simple definition of an electronic signal is a mode of communication that is generated through electric means. This refers to an electric current that is passed in an electromagnetic field.
What is the difference in parallel circuit and series circuit?
In a series type circuit, the electric current passes through each element of the circuit (light bulb or whatever) in sequence; it does not reach any element until it has first passed through all the earlier elements. In a parallel type circuit, every element of the circuit receives its electric current independently. A separate wire connects each element to the source of the current rather than to the previous element of the circuit.
How is energy passed in parallel circuit?
so you have circuit it just goes right through
Why would electricity go off if too many appliances are running?
Circuit breakers are in place to prevent an over-current condition. When too much current is passed through a wire, it overheats and can result in fire. The circuit breaker is just doing its job when it turns off a circuit in that kind of condition. Too many appliances running simply means too much current on a circuit.
What happen when electric current is passed through water'?

Do the conductors charge when a current is passed through them?
yes
Does copper get heated when electric current is passed through?
yes it does
