Intended Grade Level(s):
Learning Goal(s):

Students will understand that voltage is a measure of a difference in electric potential energy and that current is the rate at which charge flows through a circuit.

Students will understand how to measure and quantify electricity.

Students will become familiar with the relationships between the fundamental electrical

Estimated Activity Length:
1 hour 30 min

Students will set up a simple circuit using a solar module and three small loads. They will then use a multimeter to measure the voltage across each load and the current through each circuit. Students will then calculate the power consumption and resistance of each load.
