Hey Cecil, What's this 'conservation of charge'?

From _University_Physics_ 9th edition by Young and Freedman:
"principle of conservation of charge: The algebraic sum of all
the electric charges in any closed system is constant."
Example: If one combines a proton (+1) and an electron (-1)
one gets a neutron (0) which will often decay back into a
proton (+1) and an electron (-1).

In practice, it means that if N electrons flow into both ends
of a coil during 1/2 cycle, N electrons will flow out of both
ends of the same coil during the next 1/2 cycle. Thus, current
flowing into both ends of a phase-reversing coil at the same
time does NOT violate the conservation of charge principle
when averaged over an entire cycle.
