One among others, of the reasons primary current (coil + any ballast) is limited in Kettering points and condensor ignitions is to limit the current the points have to switch to around 4 amps and under otherwise they burn up too quickly. That would be like at least 1.5 ohms at 6 volt or 3 ohms at 12 volts HOWEVER the whole system (points, coil, condensor) comes into play engineerign wise so if properly designed (to handle current and heat etc) there no reason the figures approximated above have to be exact i.e many 6 volt coils are around 1.25 to under 2 ohms and many 12 volt are 2.5 to 4 but nottttttt alllllllll of them.
