An instrument or measuring device that measures electric current
Ammeter
A continuous conducting path for current.
Circuit
The net movement of electrons through a conductor. (Often defined as the net amount of charge passing through a conductor at a given point per unit time.)
Current
A diagram that represents an electric circuit using symbols.
Schematic
A measuring device that measures electric potential, or voltage, across a component or components in a circuit.
Voltmeter
The rate at which energy transformed or work done per unit time.
Power
Essentially a measure of the work associated with moving an electric charge from one point to another.
Voltage
Property of a material that determines its ability to allow current to flow through it.
Resistance
An electrical component that restricts the flow of electric current.
Resistor
Unit of electric power, equal to one joule per second.
Watt
A device containing an electric cell or a series of electric cells storing energy that can be converted into electrical power.
Battery
The voltage across an electric device is directly proportional to the current through it and to the device's electrical resistance, usually written in the following form: V=C X R
