A Resistor and a Capacitor are two completely different animals. The condensor (which is a type of capacitor) is attached to the points so prevent arcing. The car wouldn't run very long without a condenser because the points would burn up. Another capacitor that is found on cars is in the radio ciruit or attached to the + side of the coil, to suppress radio interference. The Ballast Resistor is put on inline to a 9-volt coil to lower the current to it. The bypass circuit runs 12 volts to the coil to give it a hotter spark under cranking.
It depends on what voltage the coil is designed to run at whether the resistor is needed.
What's the number on the coil?
