Electric Potential Difference
The change in potential energy per unit charge in an electric field.
Volt
The unit equal to one joule per coulomb, 1 J/C.
Equipotential
The electric potential difference of zero between two or more positions in an electric field.
Capacitor
An electric device used to store charge that is made up of two conductors separated by an insulator.
Capacitance
The ratio of an object's stored charge to its electric potential difference.
Electric Current
A flow of charged particles.
Conventional Current
A flow of positive charges that move from higher potential to lower potential.
Battery
A device made up of several galvanic cells connected together that converts chemical energy to electric energy.
Electric Circuit
A closed loop or pathway that allows electric charges to flow.
Ampere
A flow of electric charge, or electric current, equal to one coulomb per second.
1 C/s
Resistance
A property that determines how much current will flow; is equal to voltage divided by current.
Resistor
A device with a specific resistance; may be made of long, thin wires; graphite; or semiconductors and often is used to control the current in circuits or parts of circuits.
Parallel Connection
A type of connection in which the circuit component and the voltmeter are aligned parallel to one another in the circuit, the potential difference across the voltmeter equals the potential difference across the circuit element, and there are two or more current paths to follow.
Series Connection
A type of connection in which there is only a single current path.
