How an electrical relay works?
A relay will have a control circuit and a function circuitcould be the same feed line. One set of terminals (Hot and Load) can be activated at all times, but will not function until the control circuit is closed. The control circuit has a Hot and a Ground--when activated either by supply hot or ground by switch. The internal coil closes allowing the function circuit to operate. The purpose of this relay is to reduce the spike to the alternator. It takes less current (voltage) to close the coil on the relay than it would to operate the accessory that it controls
What causes contact chatter in electrical circuit?
Overload can cause contact chatter. Once the contact closes, the voltage in the circuit collapses and that causes the relay to drop out. At this pint the relay energizes, since the voltage is back. This cycle will continue on.
What is the meaning of single pole sw?
The "sw" is electrical terminology for the word "switch". A single pole switch is one that opens the circuit when in the off position and closes the circuit when in the on position. Individual switches that turn on light fixtures in your home are in the classification of single pole switches.
What is the basic operation of 220 volts flashing lamp?
Basically the circuit to the lamp opens and closes in a specific amount of times per minute. In some models this can be varied with a control circuit that allows the operator to set how many times the lamp is to flash per minute.
How do close-circuit jacks work?
These jacks are used in audio systems to patch in a piece of outboard gear. When you plug in the cable, the circuit is interrupted and sent to the external gear. When you remove the cable, the circuit 'closes' and sends the signal on through. A headphone jack is a closed-circuit jack. When you plug in your headphones, the circuit to the internal speaker 'opens' and sound is sent only to the headphones. When you unplug them, the circuit to the speaker 'closes' and you hear sound through the speaker again.
Electrical device activated by a current that opens or closes another circuit?
An electrical device activated by a current that opens or closes another circuit is called a relay. A contactor also falls into this category.
It closes the electrical circuit.?
The definition of a switch is a device that closes and opens an electrical circuit.
What a switch does in an electrical circuit?
opens and closes the circuit
Is the key have anything to do with the car starting?
When the key is turned on, it closes an electrical circuit. That closes another electrical circuit which makes and electromagnet work. The electromagnet closes a circuit between the battery and the starter. That starts the car. So the key does not actually do any work to start the car but it tells the various circuits to get busy and start the car.

The part of a circuit that closes or opens a circuit?
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
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
Would a light switch converts electrical energy?
No, a light switch does not convert electrical energy. It simply opens or closes the circuit to control the flow of electrical current to the light bulb, which then converts electrical energy into light energy.
What is a electromechanically relay?
A relay is an electronic switching device that opens or closes a circuit. An electromechanical relay would be one that is opereated remotely using an electrical circuit that mechanically operated the relay, which in turn opens/closes the second ciruit.
How is a fuse like a switch?
A fuse is a safety device that melts and breaks the electrical circuit if there is excessive current flow, while a switch is a mechanical device that opens or closes a circuit. Both can control the flow of electricity, but the fuse acts as a protective measure against overcurrent situations, whereas the switch is used to manually control the circuit.
What is the simple device that opens and closes an electrical unit called?
A device that opens and closes a circuit is called a switch.
How does an electrical light switch work to control the flow of electricity to a light fixture?
An electrical light switch works by interrupting or completing the circuit that allows electricity to flow to a light fixture. When the switch is turned on, it closes the circuit, allowing electricity to flow and the light to turn on. When the switch is turned off, it opens the circuit, cutting off the flow of electricity and turning off the light.
