Circuits: Closing or Opening a Switch Brightness Change Problem

This lesson will look at an example problem of a circuit and explain how to solve quantitatively what happens to the voltage across, the current through and the brightness of each bulb when the switch opens.... This lesson will look at an example problem of a circuit and explain how to solve quantitatively what happens to the voltage across, the current through and the brightness of each bulb when the switch opens. This lesson will take a step by step process in solving the example problem, using a diagram to better understand the question and topic.
