Why is voltage described as potential energy per charge?
Voltage is often called an electromotive force since it causes a flow of charge. However, it is described in terms of Joules per Coulomb or Potential Energy per Charge. … High voltage, or high electromotive force, causes high current. So this means charge with high PE will cause high current. This doesn't seem to make sense to me. …

How is voltage proportional to current?
For example, I could separate some amount of charge and create some voltage. … charge a longer distance will have a bigger voltage, but a smaller force acting on it. …
