# Links for the 15th Chapter

This video discusses how electrons flow through a circuit.

This video works with resistors in series. You only need to understand the first three problems.

This video works with resistors in parallel, determining the total resistance, current, and other things. You only need to understand the first three problems.

This video shows you how to determine the total resistance of a complex circuit. He adds fractions when working with parallel circuits, but you can just use a calculator

This is a song two students made for me reviewing the three electricity equations used in this chapter.

This video shows you how a fuse works.

This video shows you how a bimetallic strip curls when it heats up.

This video shows you how a circuit breaker uses a bimetallic strip to stop excess current flow.

This video shows you the way a capacitor provides a lot of current.

This animation shows the two ways batteries can be connected to either increase voltage or current.
