I am a newbie trying to enter the world of electronics and currently struggling with getting a good grasp of basic concepts of electricity. I understand that electrons which usually produce the current are moving from points with lower potential to the points with higher potential.
Consider the following situation which confuses me:
Somehow we arranged two plates of capacitor to be charged. Consider also that positively charged plate has actual positive charge on it and negative plate has actual negative charge on it. So the upper plate is now having the higher potential than the lower plate and also has higher potential than the ground. The electrons are attracted to the higher plate by means of electric field. Now imagine connecting the lower (negatively charged) plate to the ground (assume ground's potential and charge is zero). Will electrons be moving from the plate to the ground or will they stay concentrated on the plate? And if they will move wouldn't it be opposite to the assumption outlined before?
Will the situation be different if positive charge was not present on higher plate. So the upper plate and ground have both the same zero potential?
