Emerging electricians build a simple ammeter for making measurements on an electric current. They test the placement of solar cells in both series and parallel circuits and examine the magnetic field produced by the movement of electrons...

Students explore the properties of electricity. This lab shows students the need for a circuit in order to have a flow of electricity. It demonstrates Ohm's law, which relates voltage, current, and resistance.

Students explore electricity by conducting a series of experiments. In this physics lesson, students discover the relationship between current, voltage and resistance. They calculate voltage and power in a given system.
