This Crash Course video lesson, students will learn the importance of looking at the quality of the science and the quality of the journalism for news stories.

This article from Khan Academy provides information about the properties of materials that cause a resistor to resist the flow of current. This information is intended for high school physics students.

Learn about the instruments we use to measure voltage and current. [8:17]

Sal Khan shows that there will be a net torque on a loop of current in a wire in this video. He also shows that this net torque will cause the loop to rotate. [10:35]

Watch how a wire carrying a current creates a magnetic field. [9:42]

A video explaining how voltage is created within in a battery by the chemicals inside. Learn how the energy in the battery allows current to flow through a circuit to create electricity. [4:06]
