Hi guys, I have an LED indicator light which is supposed to let me know if power is getting to a certain part of my circuit. That part of the circuit is getting ~173 VAC. I have only a 110 VAC LED indicator. I figure I need to put a resistor in series with the LED, but I'm really not sure what value, or how to do the analysis. The LED indicator I have is designed for 110 VAC, but I'm not sure how. Its in a small case so it may have some circuitry like a diode and/or capacitor. Could you let me know if an LED in series is the best way to drop the voltage for the LED (I'm really limited here since I can't change the circuit or the LED directly)? Also how would one do the analysis be hand to determine how much voltage will be dropped across the resistor (assuming I know how much current the LED takes, which I don't). Thanks.
