Circuits
Students draw a schematic diagram of parts needed to build an op-amp. For this physics lesson, students test the operation of their machine. They graph and analyze data using excel.

Electric Current and Circuits
Compare the drift speed of conduction electrons in a current-carrying wire to the signal speed of changes in current. They also distinguish between DC and AC and describe how AC is converted to DC.
Curated OER
Electric Circuits
Students model the flow of electrons in a circuit, draw diagrams of an electric circuit and build an electric circuit. Students explain how to tell when the path of an electric circuit is complete, and test the conductivity of a variety...
