Greetings, I am a high school student that is trying to learn about electronics and circuits for a hobby, and I just cannot understand voltage. Some resources are telling me that it is a "potential difference" between two points, while other resources are telling me that it is simply the electrical force being exerted at a certain point. With the first definition, I am under the impression that two points are needed to measure voltage, while with the second definition, voltage can be measured at one single point. Could someone explain to me what voltage exactly is in the most basic form possible? Help would be greatly appreciated! Thank you.
