ammeter - a(n) blank is an instrument for measuring electrical current current - measured in amperes, blank is the flow of electrons in a circuit volt - blank are the force required to produce a current of on ampere through a resistance of one ohm voltmeter - voltage is measured with a(n) blank amp - blank are the basic unit of measurement for electrical current joule - one volt is the potential difference between two points for which one coulomb of electricity will do one blank of work ...

Appliances - Equipment designed for a particular purpose (for example, using electricity to produce heat, light, or mechanical motion) Appliances are usually self-contained, are generally available for applications other than industrial use, and are normally produced in standard sizes or types. Bonding bushing - A special conduit bushing equipped with a conductor terminal to accept a bonding jumper. It also has a screw or other sharp device to bite into the enclosure wall to bond the conduit...

90 degree bend - A bend that changes the direction of the conduit by 90 degrees Back-to-back bend - Any bend formed by two 90 degree bends with a straight section of conduit between the bends Concentric bends - 90 degree bends made in two or more parallel runs of conduit with the radius of each bend increasing from the inside of the run toward the outside Developed length - The actual length of the conduit that will be bent. Gain - Because a conduit bends in a radius and not at right angle...
