Voltage in a DC circuit

Hi guys:
I like physics but i have many questions concerning electricity and magnetism.
1- Do we accelerate electrons when increasing the voltage in a DC circuit.
2-What does it mean when we say there is a potential difference across the plates of the capacitor.
3- What is the potential and potential difference???? please with photos and simple explanation and so confusing for me
4-What is the ground voltage ? so confusing for me.
5-Why is current directly proportional to the voltage because the higher the voltage the higher the speed of electrons and thus more electrons pass through a piece of wire in a period of time ?????
is the previous explanation a right understanding of Ohm's law.
I would be really grateful for your answers.
Thanks in advance.

. . . . . and then come to us with one question at a time.

There's just too much here, for one thread but it reads as if you need a proper course on electricity, rather than 'bits and bobs' of specific answers.
