A current is a flow of electricity. Electricians have units of measure that describe its speed, the ease with which it flows or the resistance.

1. Ampere
   Kilocalorie
2. Ohm
   Volt

Of course, it's kilocalorie. Technically, what we think of as a "calorie" is actually a thousand calories, a literal calorie being a very small measure of the energy potential of food.

1. Closed
   Infinite
2. Open
   Defined

Circuits must be closed to function properly. "Infinite loop" is a term from computer science, not electrician work.

1. Anode
   Conductor
2. Inductor
   Transponder

Something that allows current to flow through it easily is called a conductor. "Conductive" is the adjective term. Many metals are great conductors.

1. Copper
   Gold
2. Silver
   Brass

Surprised? Silver is actually a better conductor than copper, but copper is much less expensive. Gold ranks third.

1. Low atomic weight
   High water content
2. Free electrons
   An extra proton

Electric current is the movement of charged particles -- almost always negatively charged electrons. Substances with free electrons are "ready to move," in this sense.

1. Cotton
   Diamond
2. Water
   Wood

Most people, regardless of their line of work, know this. It's important to an electrician's work because water on a job site can be dangerous.

1. Deductive
   Inductive
2. Insulating
   Substrating

The opposite of a conductive material is an insulating one. "Insulation" takes its name from "insula," the Latin word for "island," and refers to a substance's ability to shield you from electricity.

1. Airplanes
   Cars
2. Utility poles
   Electricians work on all of these.

An electrician might specialize in the field of aviation, shipbuilding, public utility lines, high-speed data cabling and more. But in the theater, an "electrician" is a lighting technician. He or she isn't usually a union electrician who is part of the Apprentice/Journeyman/Master system.

1. Poleman
   Lineman
2. Telecom worker
   Utilitarian

Don't yell at us about the sexism of the term, please, we didn't invent it! Fewer than 3 percent of electricians are female -- which is a shame, because a veteran electrician can make serious bank.

1. Ampere
   Coloumb
2. Volt
   Watt

The "volt" is named for physicist Alessandro Volta. "Difference in electrical potential" is a relatively complicated concept, also known as "electrical tension." (Which doesn't clarify much).

1. Yes, it can.
2. No, it has to be used as it's generated.

Of course electricity can be stored! That's the basic function of a battery, after all.

1. A drum auger
   A multimeter
2. Needle-nosed pliers
   A wire stripper

A drum auger is a plumber's tool. Augers in general are called "drain snakes," and are are used to clear clogs. We probably should have said that an electrician would be VERY unlikely to need this.

1. Amps
   Code
2. Hoyle
   Tome

"Code" is the term for the set of safety rules that a jurisdiction sets. If you chose "Hoyle," you were probably thinking of the expression "according to Hoyle," which is a figure of speech, and not actually official!

1. Coulomb
   Joule
2. Watt
   Farad

The coulomb is the charge carried by a current of one ampere over one second. It, like most terms in electricity, is named for a scientist, Charles-Augustin de Coulomb.

1. Capacitance
   Permitivity
2. Resistance
   Volume

This is the root of the word "capacitator," a device used in electrical engineering. Capacitance is measured in "farads," named for physicist Michael Faraday.

1. Alternating current
   Moderated current
2. Variable current
   There is no name for this.

The term for this is alternating current, or "AC." Most homes are wired in AC.

1. Exact current
   Direct current
2. Dilated current
   Variable current

This might be familiar to you from the band name AC/DC. Who knew metal could be useful in a trivia quiz completely unrelated to music?

1. Direction of current
   Volume of current
2. Potential for work
   Resistance

Resistance is the difficulty with which electric current flows. So what's the difference between that and insulation? Insulation is inherent to the material; for example, rubber is highly insulative by nature. Resistance changes when the shape of the conducting material is changed -- for example, a thick versus a thin wire.

1. It looks nice.
   It performs well in extreme cold.
2. It resists arcing.
   It resists tarnishing.

Fun fact: Neither gold nor diamond are particularly rare. They were first valued for their durability, and eventually became status symbols. Therefore gold, despite its use in jewelry and value as an investment, is still used as a conductor in electronics when tarnishing is a concern.

1. Charge built up in a battery
   Insulativity
2. Rate of current flow
   Direction of current flow

The word "amperes" is often shortened to "amps." We're not sure how "amped" became a slang term meaning "excited," except that hey, it's got to do with electricity, and that was probably enough.

1. An anode
   A cathode
2. A semiconductor
   A superconductor

Superconductivity isn't a phenomenon often found in nature, or everyday engineering. A superconductor requires very cold temperatures, for one thing. Most electricians will never have to deal with one.

1. Circuit breakers
   A cooling fan
2. A master diagram of the house's wiring
   All of these

The service panel, or "breaker box," is where you go after part of your home loses electricity, to see which circuit was tripped. Then you curse yourself for never adequately labeling the circuits.

1. No, it's too dangerous.
   Yes, and sometimes it's a good idea.
2. No. It's safe, but they'll have to pay an electrician to turn it back on.
   It's impossible to do so.

It's easy to trip a circuit and then restore it. In fact, if you're going to do repairs on an appliance or replace a lighting fixture, this is a good safety precaution.

1. Yes
   No, but they're close.
2. No, they're hugely different things.

A circuit breaker and a fuse serve the same purpose -- they keep current from exceeding a maximum amperage. But fuses melt, whereas circuit breakers "trip" or break the circuit, shutting off the current. They can then can be reset.

1. Recall
   Ground
2. Safety
   There is no name for this

This is called an "earth" in other parts of the world. It's an important safety precaution. You don't want to stand in for the ground in an electrical system!

1. A receptacle box with proper grounding
   A basic toolkit for electricians
2. The female part of a receptacle box
   The main electricity panel outside the house

You'll hear this called the "main box" sometimes. The exterior is waterproof, so it won't be harmed by rains.

1. Yes, there is.
2. No, just a "multimeter"

A voltmeter tests the difference in electrical potential between two points in a circuit. A multimeter has this function, but also might measure resistance or amperage.

1. True
2. False

Lightning is a grand, highly visible example of static electricity, not electric arc. Arcing is a rarer phenomenon, and a little more complicated to explain.

1. A current running backward between two poles
   A gas breaking down to create electricity between two poles
2. Electric current created by an organism, e.g. an electric eel
   Electric current in water

Electric arc is one of the more complicated concepts in electrical engineering. However, it has its uses -- public streetlamps used to make common use of electric arcing, and movie projectors still do.

1. Ground Fault Circuit Intensifier
   Ground Fault Circuit Interruptor
2. Ground Fault Circuit Interior
   Ground Fault Circuit Internment

A GFCI is a protective device that shuts off current to prevent injury. Receptacle boxes in walls have them, and they should be tested regularly to ensure they're still working properly.

1. Oxidation
   Photosynthesis
2. Magnetism
   Wind

In physics, the terms are sometimes combined as "electromagnetism." At the center of both are the workings of positive and negative poles or charges.

1. Base
   Jacket
2. Ribbing
   Strip

This might be the only area where fashion and electricianship overlap!

1. Because one connects to the "hot" wires and one to the neutral wire
   Because one conducts protons and one conducts electrons
2. Because one is for 15-ampere current and the other for 25 amps
   No one knows.

This is so you can only insert the plug one way. This way, the prong for the hot and neutral wires are always in the correct place.

1. Electricians
   Carpenters
2. Auto mechanics
   Stadium and theater lighting technicians

This shouldn't surprise anyone, though you might have thought that electricians are safer on the job because of their specialized training. Sadly, this isn't so, according to occupational-safety stats. It underscores the need for good training and refresher courses.
