CURRENT RELAY CIRCUIT
A current relay is switch that utilizes an armature powered by an electromagnet in order to complete an electrical circuit. Relays are commonly used to operate the circuits that provide power to motors and lights. Relays are simple devices that are comprised of four basic components.

wwwtronics-tutorials›Miscellaneous CircuitsEmitter Darlington Relay Switch Circuit. The Common Emitter Darlington relay switch circuit is useful to provide current gain and power gain with the voltage gain approximately equal to unity. Another important characteristic of this type of Emitter Follower circuit is that it has a high input impedance and a low output impedance,..

How to Make Relay Switch Circuit - Engineering Projects
A relay is a device by which electric current flowing in one circuit can open or close a second circuit i.e. switch the current ON or OFF in the second circuit. Working of the electromagnetic relay: The operating circuit (circuit 1), see the figure 1, is connected to a solenoid coil wound round iron core.
Circuit breaker - Wikipedia
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume[PDF]

Some relays have both ÒbÓ and ÒaÓ contacts, and the prefix before the actuating quantity in their name is Òover-and-under.ó In protective-relay terminology, a ÒcurrentÓ relay is one whose actuating source is a current in a circuit supplied to the relay either directly or from a current transformer.

wwwtronics-tutorials›Input/Output DevicesThe Electromechanical Relay. Such relays are used in general electrical and electronic control or switching circuits either mounted directly onto PCB boards or connected free standing and in which the load currents are normally fractions of an ampere up to 20+ amperes. The relay circuit are common in Electronics applications.
How Relays Work | Relay diagrams, relay definitions and
Relays involve two circuits: the energizing circuit and the contact circuit. The coil is on the energizing side; and the relays contacts are on the contact side. When a relays coil is energized, current flow through the coil creates a magnetic field.
Relay - Wikipedia
Since relays are switches, the terminology applied to switches is also applied to relays; a relay switches one or more poles, each of whose contacts can be thrown by energizing the coil. Normally open (NO) contacts connect the circuit when the relay is activated; the circuit is
