My Tank Thread
True, I explained why I simplified it here in post #31I have a small quibble with what you said in your opening post. You said " Electricity always takes the lowest resistance path to ground." That suggests that it ignores the other paths.
That is somewhat misleading. Electricity takes all paths available to it. Most of the current will go through the lowest resistance path if the other paths are much higher in resistance. There will still be some current flowing through the other paths.
