I thought that was obvious.Thank you ScottWang and spinnaker. I did consider the Hall Effect Sensor earlier. Can you please tell me why you think the series resistor is a bad idea ? Is the Hall Effect Sensor more accurate than using a series resistor ?
One thing usually overlooked by those using this scheme is you are intentionally breaking the safety bond between neutral and ground by that very same sense resistor.Can you please tell me why you think the series resistor is a bad idea ?
