Class Vocabulary
ammeter		A device used to measure current flow.
amp		The shortened term for ampere.
ampere		A unit of electrical measurement that describes both an amount of electricity and the time it takes for electricity to travel a certain distance. One amp equals one coulomb per second.
capacity		The amount of electricity that can safely flow through a wire without the wire overheating.
control		A part or component in a circuit that controls the flow of electricity.
coulomb		The smallest quantity measurement of electrical current. A coulomb may be thought of as a "drop" of electricity.
current		The flow of electricity. Current is measured in amps.
de-energized		When power retained by sophisticated electronic devices is removed with a special shorting instrument.
direct current		Current that travels in one direction. Direct current does not reverse the direction of flow.
directly proportional		A relationship where a number increases or decreases together with another number at the same ratio. Directly proportional is the opposite of inversely proportional.
electromotive force		The force that pushes electrons through a conductor.
in parallel		When current passes through separate components in a circuit simultaneously because there is more than one path for current to flow.
in series		When current passes through all components in a circuit one after another because there is only one path for current flow.
inversely proportional		A relationship where a number either increases as another decreases or decreases as another increases. Inversely proportional is the opposite of directly proportional.
joule		The amount of power used when 1 amp flows through 1 ohm for 1 second.
Kirchoff’s Voltage Law		The universal truth stating that the sum of the voltages around any closed loop must equal zero.
load		The part or component in a circuit that converts electricity into light, heat, or mechanical motion. Examples of loads are a light bulb, appliance, or machine.
multimeter		A device that combines the functions of an ammeter, voltmeter, and ohmmeter.
ohm		The unit of measurement for electrical resistance.
Ohm’s Law		The universal truth stating that it takes one volt to push one amp through one ohm.
ohmmeter		A device used to measure resistance.
path		A conductor that directs electricity in a circuit. The path is often copper wire.
power		The rate at which a device converts electrical energy into another form, such as heat or light. Power is measured in watts.
resistance		The opposition to current flow. Resistance is measured in ohms.
resistor		A device that restricts current flow and produces work, such as heat.
series circuit		A route for the flow of electricity that has only one path.
source		The device that provides electrical power to a circuit. The source is the origin of electricity, such as a battery or power plant.
volt		A unit of voltage or electrical pressure.
voltage		A measure of electrical pressure or potential known as electromotive force. Voltage is measured in volts.
voltage drop		The amount of voltage needed to push a given amount of current through a given amount of resistance.
voltmeter		A device used to measure voltage.
watt		A unit of measurement for the wattage or power being used in a circuit. Watts require a change in energy to exist.
wattage		The power being used in a circuit. It is measured in watts.
work		The result of electricity flowing through some type of resistance. Work appears in the form of heat, light, or motion.
