It somewhat depends on how everything set up. With a by-pass wired up when the starter is energized full voltage is applied to the coil. Cranking the starter lowers the voltage to the coil and the by-pass provides higher voltage to make it easier to start. Even without the by-pass a ballast resistor provides a higher voltage to the coil when cold and increases resistance as it heat up. A separate coil with a ballast resistor was the common factory set up. Built in resistance is simpler to set up. That is also part of why Ford used a ballast resistor on the earlier 6v coils.
