    Puzzled by how the Voltage is the same across different points

    Ah, okay, thank you, sorry! I'm trying to get this but I really don't get it :( Then, what does the elecrtical energy depend on? What is that electrical energy? How can one coulomb have more of it than another coulomb?

    Puzzled by how the Voltage is the same across different points

    Thanks. Yeah, I know. It's the difference in potential energy between two points. But why is there no difference in potential energy between two points which are places in different distances from the destination? I thought there would be less pressure there. And why does a resistor create a...

    Puzzled by how the Voltage is the same across different points

    If this is better for the HW section please tell me, sorry about that. So Voltage is the change in potential. I'm puzzled by how potential in circuits is the same along different points until we reach a resistor - at which point the potential changes. As in, if we take two points before a...
