Document Content and Description Below

An electromagnet can be switched on and off And advantage of an electromagnet over a permanent magnet is Scatters light uniformly in all directions An excellent diffuser surface is one that ... In a photovoltaic cell Light is converted into electricity Armature The rotating part of a DC motor is known as Fish tape A device used to pull wires through a conduit is called Approximately zero In making a resistance test, remember that the resistance of a short circuit is Parallel To increase current capacity, battery cells are connected in 10 The hot resistance of an incandescent lamp is approximately how many times it's cold resistance Start measuring at the highest range The proper way of measuring and unknown voltage with a multi-tester is to A charge A capacitor stores what? Paper What has the lowest dielectric strength Knife A form of air switch in which the moving element is a hinged blade wedge between stationary contact blades when closed is a what switch The contact resistance between the bare wire in the person at the point of contact If a bare live conductor is touched accidentally, the severity of the electric shock is determined primarily by The same as The voltage per turn of the primary of a transformer is ________the voltage per turn of the secondary Infinite And open resister when checked with an ohmmeter reads Lesser The larger the diameter of a wire, the _____is it's resistance? Above Service heads and goosenecks in service entrance cable shall be what point of attachment of the service drops to the building? Moisture resistant and thermoplastic Type TW conductor is what type? Low permeability Steel is hard to magnetize because of its Commutator A repulsion motor is equipped with a increase When the temperature of a copper wire is raised, the resistance will Starting The capacitor in a capacitor-start induction-run AC motor is connected in series with what winding? Cover Defined as the shortest distance measured between a point on the top surface of any direct buried conductor, cable, conduit and a top surface of finish grade A battery An ohmmeter consists of a meter movement in series with what? Oil and soap Greece is a lubricant that is basically a combination of what? Open The continuity of a coil of winding may be determined by measuring the resistance of the coil. If the resistance measured is infinite, the coil winding is what? SPDT A three-way switch is equivalent to what kind of switch? It makes the operation of each appliance independent with each other The main reason that electrical appliances are connected in parallel rather than series is? Voltage A step up transformer increases what? Inductive A circuit with a lagging current means the circuit is what? 0.4 ohms If a conductor has a resistance of 0.2 ohms and the link is doubled, the resistance becomes what? Preventing a short circuit between conducting wires Insulating materials have the function of Voltage source and a conductor For current to flow the very basic circuit requirements are [Show More]
