Students have the opportunity to explore the basics of current and circuits in this online module. Some of the activities include interactive animations, informational text, practice problems, and lab experiments.

[Free Registration/Login may be required to access all resource tools.] The definition of electric current is explained and how to calculate an electric current. Includes links to resources for learning more about electricity, i.e., a...

This lab was designed to have students test the factors that determine how much current is induced in a circuit when area of the circuit is changed. This lab is a quantitive lab that supplements the lab on magnetic flux.

Students explore with a PhET interactive simulation to replicate the construction of electrical circuits.

This lab is designed to have students investigate the relationships between voltage, resistance and current in a circuit with only one passive component. The batteries in this simulation can be varied from ideal batteries to batteries...

This lab was designed to help students understand the difference between circuits powered by DC and circuits powered by AC. Students can see that simple changes in frequency lead to changes in the potential difference across the...

This lab was designed to have students test the factors that affect the acceleration of a metal bar that is carrying a current through a magnetic field.

This lab was designed to help students understand the difference between circuits powered by DC and circuits powered by AC. Students can see that simple changes in frequency lead to changes in the potential difference across the...

This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the...

Electricity goes through some ups and downs on its way from the power plant to your house. See how it works in this interactive activity.

A guided inquiry that involves observation of the parts of a light bulb in a lab.

Investigate with a bar magnet and coils to learn about Faraday's law. You can also play with electromagnets, generators, and transformers!

No fancy movement in this tutorial, but these rules come in very handy when trying to understand some of what's going on in our other tutorials.
