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.
