In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.
