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...

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...

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...

[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...

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 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...

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...

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....

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a...

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