| Question | Answer |
| _____ is the common name given to the end of a wire connection. | Plug |
| _____ or _____ is the name given to the female end of a connection. | Socket, receptacle |
| A receptacle is sometimes referred to as a _____. | jack |
| _____ is the name often given to describe a tie point or termination of a wire run. | Terminal |
| There's a special type of tube socket called a _____ socket that's designed to hold a tube in the socket when the electronics system is exposed to vibration. | loctal |
| Wires or conductors can be terminated by two kinds of connectors and terminals: _____ and ____. | soldered, solderless |
| A wire and terminal are connected, and then the soft metal part of the terminal is crimped (pinched) onto the wire. This is known as a _____ terminal. | crimped |
| Two examples of solderless connections are _______ and ______. | crimped terminals, wire wraps |
| W | wire wrap |
| _______ are used as tie points to interconnect wires and cables. | Terminal blocks |
| _____ are just combinations of wires. | Cables |
| _____ permit an easy flow of electric current. | Conductors |
| The two types of copper wire are ____ and _____. | solid, stranded |
| A ______ is a type of conductor that has a resistance so low that is can't be measured by ordinary instruments. These conductors often operate at very low temperatures that are close to absolute zero. | superconductor |
| _______ is equal to 459.72 degrees Fahrenheit. | Absolute zero |
| Materials that don't readily conduct electricity are called _____. | insulators |
| In some applications, insulators are called _____. | dielectrics |
| Since a "perfect" insulator doesn't exist, current can be forced through any material. If this happens in a circuit where it's not supposed to, it can destroy the insulator. This is known as an ______. | arc discharge |
| Another kind of current flow through insulators is _______. Unlike an arc discharge, this doesn't destroy the insulator, except for rare cases when it is left unrepaired for very long periods of time. | leakage current |
| The insulation that surrounds a wire is rated by its ________. | breakdown voltage |
| A wire's ________ is the amount of voltage required to produce an arc discharge through the insulation. | breakdown voltage |
| A ______ is an "in-between" material that can't conduct current as well as a conductor, but can conduct current better than an insulator. | semiconductor |
| When referring to electron flow, positive "holes" and negative electrons are called _______. | charge carriers |
| When current flows through a wire, there are some effects that are always produced. Two examples of these effects are _____ and ______. | heat, magnetic fields |
| When current flows through a wire there's always a ______. | voltage drop |
| A ______ is a device that's used to measure the amount strain of a material or structure at the point of attachment. | strain gauge |
| The amount of force applied and the cross-sectional area of the object being acted on determines the ____. | stress |
| The amount of deformation (bending) of an object is a measure of its ____. | strain |
| One ___ equals one-thousandth (1/1,000) of an inch. | mil |
| To convert inches to mils, _____ by 1,000. | multiply |
| To convert mils to inches, _____ by 1,000. | divide |
| To calculate the circular mil area of a wire when you know the diameter, simply _____ the diameter. | square |
