    Conceptual Question about Resistance and Voltage Drop

    Thanks for your responses. I'm actually a medical student, but for one reason or another, I find myself getting obsessed with certain things that don't make sense in my head when I read about it, whether or not it's in my coursework. And the majority of people in med school, students and...

    Conceptual Question about Resistance and Voltage Drop

    Okay...if everything I said thus far is correct, then I have another question. If the battery is imparting some amount of potential energy to each coulomb of charge. And it is this potential energy that is being converted into kinetic energy to cause charges to move at a certain rate. Then if...

    Conceptual Question about Resistance and Voltage Drop

    And just to make sure, the reason a current doubles upon a doubling of the voltage is because the RATE at which the coulombs flow doubles. That is, the electric potential energy associated with each coulomb doubles, and this is manifested in terms of increased velocity?

    Conceptual Question about Resistance and Voltage Drop

    Ahhh, maybe I understand. So Zz, what you are saying is that if you have a 5 amp current going through a 2 ohm resistor, you would need a 10 V drop for each coulomb in order to maintain the 5 amp current, otherwise you'd get a "backup" of charge? And similarly, if you have a 10 amp current...

    Conceptual Question about Resistance and Voltage Drop

    I think I get what you're saying...but it still doesn't answer my question in my mind. Let's be more concrete: If I had a voltage of 10V and a resistor of 2 Ohms, the current flowing would be 5 amperes and going across the resistor each coulomb would experience a drop of 10V. If you increased...

    Conceptual Question about Resistance and Voltage Drop

    Hi, 1) Can anyone explain to me from a conceptual standpoint, why increased current leads to an increased voltage drop across a resistor? Mathematically, I know V=IR. But it doesn't make sense to me why increasing a current across a resistor would lead to a greater drop in energy per...
