A relay circuit is typically a smaller switch or device which drives (opens/closes) an electric switch that is capable of carrying much larger current amounts. Or a circuit which operates the coil or electronic actuator from one source and uses a separate power source to drive an isolated device. Generally speaking, a relay circuit is a circuit that uses a small mechanical switch or a semiconductor device (with associated circuitry) to energize a relay, which will then close a contact set to complete another circuit. This system is used by most people on a daily basis, and it is used to start a motor vehicle. The key switch (ignition switch) is turned to "start" and 12 volts (approximately) is applied to the starter solenoid (which is a big relay). The coil is energized, it shuts contacts, and the battery voltage is delivered through the heavy contact set (for high current capacity) to the starter motor. There are variations on this theme to which the term relay circuit can be applied, but the idea remains the same: a small switch of some kind controls switching in another (usually higher voltage and/or current) circuit. It could be argued that the telegraph is a relay circuit. Remember those old westerns? When a telegraph key is pushed down (thus completing the circuit), a remote (relay) coil is energized. The magnetic field created by energizing that coil pulls down an armature with the objective being to make a "click" instead of it being to close some electrical contacts. An early and dramatic application of the simple relay circuit, the telegraph, yes? A RELAY CIRCUIT DOES NOT IMPLY MASSIVE CURRENT SWITCHING. It is a means to isolate one source to another.
It is the circuit (wiring) that supplies power to a relay. The relay when supplied with power allows a circuit to energize without blowing a fuse.
This is commonly used on headlights, Heating, Air conditioning, fuel pumps, etc, etc.
A relayis an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.

What do relay and circuit breakers use?
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
What is transistor relay driver?
a transistor circuit for driving the coil of a magnetic relay.
What is the function of an LBB relay?
A local breaker backup relay is used to check the operation of distribution circuit breakers and to trip the feeder circuit breaker if the distribution circuit breaker fails to trip on an overload.
Could a relay race be used as a good model for a parallel or series circuit?
A relay race could be a good model of a series circuit. In any circuit, current flow is the daisy-chaining of electrons from atom to atom.
When is a circuit considered a dry circuit?
when contacts on a switch or relay does not melt enough surface to allow current flow

Internal circuit of an electrical relay?
basic circuit of electrical protective relay
What is an electric circuit that controls another electric circuit through a relay?
Remote-Control Circuit. Any electrical circuit that controlsany other circuit through a relay or an equivalent device.
What do relay and circuit breakers use?
No. A relay is an electric switch and a circuit breaker is an overcurrent device.
How does a 6volt relay circuit works?
The same as a 12V relay circuit, except it only needs 6V instead of 12V.
Why use relay insted of switch?
Because a switch is a 'permanent' action. A relay only completes the circuit while there is power. If there is a fault in the circuit, a switch will still allow power through, whereas a relay will break the circuit.
Why does the 59n relay keep tripping the breaker?
The 59N relay may be tripping the breaker due to circuit overload, short circuit, or ground fault. Check for any faulty connections, damaged wires, or improper settings on the relay. Ensure that the relay is properly sized for the load it is protecting and troubleshoot any potential issues in the circuit.
Where is the speedometer relay on a 2003 Subaru Outback?
There is no relay used on the speedometer circuit.
What is transistor relay driver?
a transistor circuit for driving the coil of a magnetic relay.
What is the job of the fuel pump relay?
A relay is a switch which opens / or closes a circuit
How do you replace the power relay valve circuit on 2001 Ford Taurus ses?
how do you find thepower relay valve circuit for the abs brakes
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.
