Jeremy & Brent,
The negative side of the coil is attached to a wire that leads
to the ignition points. These points intermittantly do ground out,
at a time relative to the combustion cycle of each cylinder. As these
points connect the coil to ground, the coil (which has been receiving
12 volts of electricity via the positive terminal) "collapses" which
causes a high voltage discharge out through the high tension lead.
This is the low-tension cicuit.
The high tension circuitry deals with the routing of charge to
the spark plug via the distributor cap, rotor(which selects which
spark plug lead to send the voltage to by its relative position),
and high tension leads,usually referred to as "spark plug wires".
Hope I've helped.
