Read through the course notes before watching the video. The course note files may also contain links to associated animations or interactive simulations.
Read through the class slides. They explain all of the concepts from the module.
Do the Concept Questions first to make sure you understand the main concepts from this module. Then, when you are ready, try the Challenge Problems.
Watch the Problem Solving Help videos for insights on how to approach and solve problems related to the concepts in this module.
A total of 72 Coulombs of charge is transmitted by a silver wire 1.3 mm in diameter over a time of 1 hour and 10 minutes. What is the current in the wire and the current density in the wire? If silver contains 5.8x1028 free electrons per cubic meter, what is the drift velocity of the electrons in the wire?
The potential difference between points a and b on a long wire is Vab Volts. The two points are l meters apart. What is the electric field in the wire? If the current density in the wire is J, what is the resistivity ρ of the wire?
