Electricity and Magnetism

Ampere: continuous flow or charge that we call an electric current. This is measured in amperes or amps.

Voltage: pressure in the wire that creates a difference in potential energy. We measure this in Volts.

Resistance: the tendency for certain materials to slow or impede the flow of electrons. This is resistance and we measure it in Ohm's.

Electrical current will flow through a connected conductor that does not have any gaps or empty spaces. We call those loops circuits.
