Rate in Electrical Systems

Rate in Electrical Systems. 3.3. Electric Current. Rate of electrical charge flow Voltage is the prime mover I = ? q/ ? t (electric current equals charge moved divided by the time interval) Charge is measured in Coulombs (C); current is measured in amperes (A). 1A = 1C/s.
