Students work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They learn about Ohm’s law, power, parallel and series circuits, and ways to measure voltage and current.

Ohm’s law is the basis of all electrical systems. Electrical engineers use this equation to guide the design of electrical systems. Students need a strong foundation in Ohm’s law while designing circuits on their own.
