It is. More and finer wires are used in the primary winding. These wires produce the same amount of magnetism as the 6 volt coils, so the spark power is the same. The reason that external resistors are used is so they can be bypassed with wiring that gives direct battery voltage to the coil while cranking. (it has been the way that coils have been used for a long time in cars so they start in the cold. Ford used the system on 6 volt systems, with a 4 volt rated coil and a resistor). The starter relay had an "I" terminal that provided cranking voltage to the coil directly bypassing the resistor. When cranking the battery voltage can drop to 10 volts (or 5 volts on a 6v system) thus the coil is effectively given operational voltage to help get the unit started. Jim
