Capacitor has always been the correct electrical term for the device. Condenser is strictly an automotive term. Just like the correct electrical term for the coil is transformer. In electrical terms a coil is just a single winding of wire and is also used for noise suppresion where as a transformer has two or more sets of windings. In the case of the automotive transformer the primary windinds is low voltage high current that is transformed into high voltage low current in the secondaries.
The capacitor on the side of the coil connects to the positive terminal of the coil and is used for noise suppression back into the electrical system that can cause radio interference.
