I have some 0.1" stripboard and I'm going to be using it as a power bus. I need 6 connections to 6 motors, which are at 6V, and the total amount of current will be 1A, which is quite a bit for stripboard, so what I'm thinking of doing is this:
Put a common ground for all 6 motors, but split the 6V signal in parrallel so that only 3 motors are connected to a given strip. That way, although the entire board is taking the 1A, no single strip is taking the full current, and the power through any given strip should be low enough not to melt it.
But my brain has encountered and error and will have to close: current into a circuit is the same as current out, so the common ground WILL have to handle the full amp of current, right? Will the voltage drop across the motors be enough to avoid burning out the stripboard, or is it the current that matters and I'll need to rig up a few grounds in parallel as well?
