Webb7 feb. 2024 · The disadvantage of a resistor is that it allows a small current to flow in normal operation of the relay (unlike a diode) and is not quite as effective as a diode in suppressing voltage spikes, but it is less susceptible to accidental damage because resistors are not sensitive to polarity (i.e. it doesn't matter whether +12V is connected to … WebbThis theory holds true if the current draw between the three phases is balanced. Phase balancing is easy if all three phases are going to the same load, such as a motor. As long as the motor is working correctly, the current draw per phase is about the same, and the smaller, shared NEUTRAL is not a problem.
