I have a circuit and it has a cap that has around 680V and the high current that is pull it 4.22A. I need to add an LED to let me know when the Cap is drain. The problem I am having is that since the voltage and current are so high, I cant use a Hall effect sensor . I cant find one rated for that much voltage. I could do a voltage divider and have R1 be 600 ohms and R2 needs be 22 ohms but I cant find a resistor rated for 2911.8 Watts. Can someone help me ?(adsbygoogle = window.adsbygoogle || []).push({});
