What size resistor should I use to shorten a string of Christmas lights? Answered
I need to shorten a string of christmas lights from 20 lights to 3 lights.
The unaltered string ratings are 120volt, .08 amps.
The bulbs/lamps are 6volt and .48 watts each. It is interesting to me that 20 lights x 6volts = 120volts.
I'm sure that is not by coincidence but I'm not an engineer so I don't know how to use that information.
I need to know what size resistor I need to use. This is way to confusing for me to follow.
If someone can help me out with a simple formula I would appreciate it as I need to work with
lights strings of many different lengths. Please try and put your answer into laymens terms.
