Current. I: A measure of the flow of electrical charges in a conductor, such as a wire, in ampere units.
`: The quantity of current over a 1-sec period in Coulomb units (Q = I x t).
Electromotive Force. EMF: A potential difference in the system that causes a current to flow in volt units (V).
Resistance. R: A discrete element in an electrical system that opposes the flow of current in Ohm units.
Capacitance. C: Property of a pair of conductors separated by an insulator (dielectric) in Farad units.
Inductance. L: Property of a device, usually a coil of wire, that acts to oppose the flow of current by inducing in the device an opposing voltage, in Henry units.
Energy. W: Considered as the amount of work a system is capable of doing measured in Joules (1 Joule = 1 Newton-meter; N-m).
Power. P: Rate of doing work in watts (P = w/t) 1 watt = 1 Joule/sec.
Horsepower, hp: One horsepower (hp) = 746 watts = 2546 Btu/hour.
Efficiency: Defined as Power delivered to load/Power generated = P0/Pi x 100
Regulation: Defined as No load voltage - Full load voltage/Full load voltage x 100
Gram-Calorie: Energy required to raise the temperature of 1 gram of water 1 degree centigrade.
Mechanical Force: F (newtons) = mass (kg) x acceleration (m/sec2)
