Electrical units

Farads

Capacitance

Coulombs

Charge An electrical charge equal to 6.25 x 10^18 electrons

Ampere

Current A unit of measure of the rate of current flow. One ampere equals one coulomb per second.

Joules

Energy The SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one metre in the direction of action of the force, equivalent to one 3600th of a watt-hour.

Hertz

Frequency Equal to one cycle per second.

Henrys

Inductance

Watts

Power the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.

Ohm

Resistance A unit of measurement of electrical resistance. Resistance is the opposition of the flow of something

Volt

Voltage The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit.
