I picture a resistor as a bottleneck, in that the entire circuit is limited by the resistance of the most resistant component. Why do resistances in series add together? I don't understand. So, increasing voltage increases current because higher voltage means a higher disequilibrium from the source, meaning more "pressure" on the electrons to move? Given a fixed wire diameter, does that means higher voltage would make electrons move faster? Here is what I don't know or have questions about:ġ. It would only change if you increased the average negativity charge density in the negative terminal? The quantity of voltage in a battery would not change if you increased the size of the battery. Measures of voltage determine the work which can be done as a result of the imbalance? Voltage must be measured between two points, because it can only exist in relation to an imbalance between one point and another. This means that given a sufficient conductor, the electrons will do work by moving to a state of equilibrium to correct this imbalance. It represents an imbalance of charge distribution. Ill explain what I know, and what I don't, and I have some theoretical questions which I hope will help give me a better understanding.ġ. I could explain (regurgitate) the definition of voltage in many ways, and plug it into equations, but when it comes to testing my fundamental understanding of it as a natural concept, I fall short. I've done much research on these forums and through texts, and come across answers that seem quite well thought out, but still cant grasp the fundamental concept of what voltage is. For some reason, I feel like the concept of voltage is escaping my grasp.
