Not quite right. With the points closed the condenser is discharged as =
it is connected across the points. When they open it charges up, as the =
coil is discharging. The current/voltage characteristic of a condenser =
(aka capacitor) is 90 degrees out of phase with an inductor i.e. the =
coil. This makes it a tuned circuit as in a radio, and an oscillation =
is set up, which increases the HT amplitude and its duration. That's =
why an engine will always run badly without a condenser, and may not =
even run at all, depending on several other factors.

Not true, Max. When the points open, the condenser discharges through =
the coil in order to perpetuate the spark. Without the condenser the =
engine may not even start. Try it some time. :-)
