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.
