I was thinking about this, this morning and couldnt work out the answer. Its a back to basics sort of question about power.
The input jack of a guitar pedal has the battery power neg connected to it, which is broken unless a cable is plugged in. The plus is connected to the circuit. The question is, why cant the power flow from the plus of the battery to the ground of circuit, even if the negative is disconnected? Ground is still there. I have 2 possible answers not sure if either are correct although im leaning toward 2): 1) makes no difference if the battery has a connection from plus of the battery to ground, there has to be a completed circuit between the + and - of the battery terminals before current flows or 2) i have read current flows in reverse, therefore if the negative lead is disconnected from the battery, current wont flow 'out of the battery'.
Or a 3) option if both are the wrong answer?
Thanks for your help as always
