What is the formula for the voltage across each field coil? a) voltage across each field coil = field current * resistance of each field at 75°C b) voltage across each field coil = field current / resistance of each field at 75°C c) voltage across each field coil = field current + resistance of each field at 75°C d) voltage across each field coil = field current – resistance of each field at 75°C
