direction, and that the amplitude of current is determined by
the number of electrons flowing past a point in a circuit in one
second. If, for example, a coulomb of electrons moves past a
point in a wire in one second, and all the electrons are moving
wire is one ampere. Similarly, if half a coulomb of electrons
moves in one direction past a point in the wire in half a
second, then reverses direction, moving past the same point in
the opposite direction during the next halfsecond, a total of
one coulomb of electron passes the point in one second. The
preceding comparison of dc and ac is
