I am making a LED flasher with 10 set frequencies on a 555 timer circuit. I have been looking through resistors to see which to use. they have different power ratings in watts. The power supply for the circuit is 15 v with output of 200ma with I think makes it 3w. what I am unsure of is if this full power is actually going through the resistors?
I set up the circuit and used a multi meter to try and measure the amps but could not get any readings across the resistor or across the whole circuit. I and unsure why not. but could someone help find which power rating I need on my resistors
