8.02x – Lect 9 – Electric Currents, Resistivity, Conductivity, Ohm’s Law

When positive charges move in this direction, then, per definition we say the current goes in this direction. When negative charges go in this direction, we also say the current goes in this direction, that’s just our convention. If I apply a potential difference over a conductor, then I’m going to create an electric field […]
