DIRECT CURRENT n. 2 definitions
irection only; -- distinguished from alternating current. When steady and not pulsating a direct current is often called a continuous current.
IMPEDANCE n.
to the flow of an alternating current, analogous to the actual electrical resistance to a direct current, being the ratio of electromotive force to the current. It is equal to R2 + X2, where R = ohmic resistance, X = reactance. For an inductive circuit, X = 2pfL, where f = frequency and L = self-inductance; for a circu…
VOLT AMPERE n.
A unit of electric measurement equal to the product of a volt and an ampere. For direct current it is a measure of power and is the same as a watt; for alternating current it is a measure of apparent power.
