Pass/fail limits for these components seem pretty wide.thatguy, Thanks, I am starting to understand. So if I did all this and found .382v DC, would that mean my t'pile is good, or bad, or weak?
By "electro tech forum" - do you mean "ELECTRICAL FORUM" on this website?
I hear what you say about anti-virus s/w makers. Who knows what they are up to.
I am surprised to hear its not an issue on Apple! I'd be creamed on PC without it. And I still have not found one I really like. McAfee is seeming effective, but updates daily and stops me from working for about 15 minutes whenever it updates. It's free with my ATT DSL internet though.
If the load voltage is half that of the open circuit voltage then maximum power is transferred from source to load and this is desirable for a setup like this.
Run some experiments. Your t'pile can be simulated with a D cell and two 6.2 ohm resistors and your valve with a 3 ohm resistor.
Some t'couples only put out 28 mV but I can't find a spec on their internal resistance.
