Electricity correct answers General term for the variety of phenomena resulting from the
presence and flow of electric current

Volts
Amperes (amps)
Ohms correct answers 3 ways Electricity is measured

Volts correct answers Measure the difference of potential between 2 points

Amperes (amps) correct answers Measure the number of electrons that move past a specific point
in 1 second
(i.e. electrical currents)

Ohms correct answers Measure resistance, including anything that could limit the flow of
electrons

Current correct answers Electrical ___ occurs when electrons move from one place to another.

Conductors
(e.g. copper, silver, water) correct answers A substance, body, or device that conducts electricity;
allows the electrons to move freely.

Insulators
(e.g. rubber, wood) correct answers A material of such low conductivity that does not easily
allow the flow of electrical current to pass through it; discourages electrical current

Watt correct answers This measures power, the rate at which electrical energy is consumed or
transformed into another type of energy, such as light or heat

Power correct answers The rate at which electrical energy is consumed or transformed into
another type of energy, such as light or heat

Watt-hour correct answers This is the amount of energy used in 1 hour at a rate of 1 watt.

Kilowatt-hour correct answers The amount of energy used in 1 hour at a rate of 1,000 watts(i.e.1-
kilowatt)

True correct answers True or False
Most electricity is measured in kilowatt-hours

Wattage x Time (expressed in hours) correct answers To find watt-hours multiply ___ by ___.

10 kilowatt-hours correct answers How many kilowatt-hours is enough energy to run a 10,000-
watt speaker system for 1 hour?

, 2 hours correct answers 10 kilowatt-hours is enough energy to run a 5,000-watt air conditioner
for how long?

10 hours correct answers 10 kilowatt-hours is enough energy to run a 1,000-watt waffle iron for
how long?

Circuit correct answers The path of an electrical current

Open correct answers When there is literally an open space in the circuit that prohibits current
from flowing

Short correct answers When the open space of a circuit has been closed to allow current to flow

Voltage correct answers The difference of the pressure between 2 points in a circuit
(sometimes called voltage drop or difference of potential)

True correct answers True or False
To see what the voltage is anywhere in a circuit, you have to compare the voltage at that point to
ground

Ground
(e.g. base of a lamp, chassis of a car) correct answers Any part of a circuit (or other object that
has electricity running through it) that measures 0 volts

Voltmeter or multimeter correct answers Measures voltage in a circuit

Voltmeter correct answers An instrument used for measuring electrical potential difference
between two points in an electric circuit (i.e. voltage)

A voltmeter has 2 leads. To measure voltage, you place one lead somewhere in the circuit and
one lead at another location in the circuit. The voltmeter tells you what the voltage is between
those 2 points. correct answers How to use a voltmeter:

Cell correct answers A storage compartment for electricity in a battery that has a specific
voltage.

True correct answers True or False
You can figure out the number of cells a battery has by dividing the voltage of the battery by the
volts.

Electrical current correct answers The flow (rate of flow) of electrons in a conductor

coulombs (C), which measure charge. correct answers Current flow can be expressed in terms of
___.
