material, eg copper, has lower resistance than steel length - longer wires have greater resistance thickness - smaller diameter wires have greater resistance temperature - heating a wire increases its ...

Four factors affecting the resistance of a wire are described. Ohm’s Law: Four factors affecting the resistance of a wire are described and students learn how to solve problems using Ohm’s Law. Ohm’s ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
