Simple homemade batteries are described that can be made from items found in the home or school lab. These experiments help students understand how to wire them up, the origin of current, voltage and power, as well as the chemistry that...

In this interactive simulation of Ohm's law, adapted from the University of Colorado's Physics Education Technology project, students will adjust the voltage and resistance in a circuit, and observe how this affects the flow of current....

Provides a long list of physics formulas for easy reference.

This lab is designed to have students investigate the factors that affect the rate at which a capacitor charges. Students can change the resistance and capacitance in the circuit and monitor the current, voltage and charge on the...

Explains and illustrates the meaning of series connections. Discusses the voltage-current-resistance relationships for series connections of resistors. An example problem on series calculations can be accessed from this page.

Explains and illustrates the meaning of parallel connections. Discusses the voltage-current-resistance relationships for parallel connections of resistors. An example problem on parallel calculations can be accessed from this page.

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

Joseph Henry was an American scientist who pioneered the construction of strong, practical electromagnets and built one of the first electromagnetic motors. During his experiments with electromagnetism, Henry discovered the property of...

Manipulate the voltage and resistance for a simple circuit to see how these affect the amount of current. The symbols in the Ohm's Law equation grow bigger and smaller to emphasize the changes.

This lab is will allow students to vary the resistance of a light bulb and the voltage difference across a light bulb. They will be able to see how these two factors affect the current through the light bulb and the power used by the...

Lord Kelvin (William Thomson) developed electrostatic theory and a range of novel and interesting electrostatic apparatuses. Described here is a reconstruction of a water dropper electrostatic generator. It's capable of generating...

[Free Registration/Login may be required to access all resource tools.] For this lesson, students learn about the invention of the battery and how a battery works, and about resistance in an electrical circuit. As well, Ohm's Law is used...

This lab is designed to have students investigate the factors that affect the rate at which a capacitor discharges. Students can change the resistance and capacitance in the circuit and then monitor the discharging of the capacitor....

Experience the photoelectric effect by choosing different light frequency, voltage, and metals to stop current from flowing in a circuit.
