Electric Current


	Electric current is the rate at which electrons flow through a cross section of a wire. This Demonstration illustrates the motion of this directed flow, which is random zig-zag at a microscopic level, causing the electrical resistance. The unit for electric current is the ampere, equal to 1 coulomb per second.
