logic circuit
logic circuit electric circuit whose output depends upon the input in a way that can be expressed as a function in symbolic logic ; it has one or more binary inputs (capable of assuming either of two states, e.g., "on" or "off" ) and a single binary output. Logic circuits that perform... Read more |

potentiometer
potentiometer 1 Manually adjustable, variable, electrical resistor. It has a resistance element that is attached to the circuit by three contacts, or terminals. The ends of the resistance element are attached to two input voltage conductors of the circuit, and the third contact, attached to the... Read more |

circuit breaker
circuit breaker electric device that, like a fuse , interrupts an electric current in a circuit when the current becomes too high. The advantage of a circuit breaker is that it can be reset after it has been tripped; a fuse must be replaced after it has been used once. When a current supplies... Read more |

relay
relay electromechanical switch operated by a flow of electricity in one circuit and controlling the flow of electricity in another circuit. A relay consists basically of an electromagnet with a soft iron bar, called an armature, held close to it. A movable contact is connected to the armature in... Read more |

short circuit
short circuit abnormal connection of low resistance between two points of a circuit that usually causes a high, potentially damaging current to flow. To protect against damage, devices such as a fuse or a circuit breaker are used. They sense the excess current and break the circuit so that no... Read more |

rheostat
rheostat , device whose resistance to electric current depends on the position of some mechanical element or control in the device. Typically a rheostat consists of a resistance element equipped with two contacts, or terminals, by which it is attached to a circuit: a fixed contact at one end and a... Read more |
