or an earbud. Also there is the old saying electricity takes the path of least resistance. Actually it takes all paths. The high value resistor would have the headphone connected across it and the low value resistor would be the ear bud connection. Let's take a look at those voltage and current values.
First the high Z tap. How much power would 30mv at 30ua be?Would it be enough to drive the headset?
Now I just need a little shop time for the build.
