If I have a power source (4V and 50 mAmps) going into a motor that is 4V with a running current of e.g. 200mAmps. What will happen? e.g. will the current from the power source just heat the motor? Or if I had a capacitor attached to the motor that was e.g. was 4V and 200mAmp...would a charge build in the capacitor and then discharge sporadically into the motor? when I think of volts I think of an electrons "height" and when I think of current I think of how many electrons are flowing. so my thought is that the height (volt) is sufficient and the current will build on the capacitor (dam) until it bursts/discharges.
