== == Yes, there are 3-way dimmer switches.
Normally staircase lights plus bed room lights need these kind of 3-way
switches to turn lights on or off from more than one place. Such lighting arrangements can use dimmers if u need as usual nothing to worry. A dimmer will help save energy, may prolong the life of the bulbs, and will permit greater variability of the amount of light to be used.
Generally relays or contactors If you are talking about an electric panel in your house, they are called breakers.
A device or circuit that provides power to the rest of the circuit or system is called a power supply,
That function was traditionally implemented in the form of a mechanical deviceknown as a "switch".The practice became so firmly embedded in the art and science of electricitythat the word became the generic term for any device that could performany similar function, so that now we have "switching transistors", integrated"CMOS switches", and even central office telephone-circuit "switches".
This is what is known as a "short circuit".
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.

That is called a 4 way light switch circuit. On each end of the circuit you install a 3way switch and in the middle you install a 4 way switch.Answer using British TerminologyIn the UK, 'three-way' switches are called 'two-way' switches (more logical, if you think about it!), and the 'four-way' switch is called an 'intermediate' switch.
Simple parts of a circuit are switches, light bulb, battery and connecting wires.
There are a few ways to find out more information about dimmers. You can talk to someone that works in electrical departments at Home Depot, Lowes, or local lighting stores. There is also an online site called How Stuff Works that explains about dimmers.
This is called a 3-way circuit. It uses special switches and wiring to control a load from more than one location.
If unaltered, it would by called a "tandem" breaker. Typically used to add new circuits to a full load center.
An operating circuit, is by definition, complete. The electrons in a DC circuit flow from the -ve terminal of the power source, through the various components and switches etc, then to the +ve terminal of the power source.
it is called a circuit and when it is closed is called a closed circuit and when open circuit it is called an open circuit
These are types of switches used in networks. A packet-switched network moves data in separate units called packets which are then assembled to create the message. Circuit switched networks send continuously but require dedicated point-to-point connections.
That is called 4 way intermediate switch wiring. Click the link to watch a video I have posted showing how to wire just such a circuit.
A kitchen on a boat is called a galley.
