Illustrated explanation of voltage, current, and resistance and the relationship between them.

In this simulation a battery will be used to charge a capacitor. The capacitor will then be used to operate a light bulb until the capacitor is discharged.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow through the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change. Java...

An interactive simulation that teaches about Ohm's Law, circuits, and current by observing how adjusting the voltage and resistance changes current according to Ohm's Law. This simulation can either be downloaded or played online and...

Using simple materials, students will learn how to create batteries, and about the relationship between voltage and current.

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

Brief explanation of Ohm's Law which provides the relationship between current, voltage, and resistance.

Explore how a capacitor works! Change the size of the plates and add a dielectric to see how it affects capacitance. Change the voltage and see charges built up on the plates. Shows the electric field in the capacitor. Measure voltage...

Students will work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. It analyzes Ohm's Law, power, parallel and series circuits, and ways to measure voltage and current.

As you put the different type of batteries on the volt meter pay attention to the voltage equations in the table. See how positive and negative numbers interact.

Explains what an LCR meter is and how it is used to measure the inductance, capacitance, and resistance of a circuit. Lists the different parameters of a circuit that it measures, describes two types of LCR meters, and gives definitions...

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 tutorial illustrates why adding bulbs to a circuit makes all the bulbs dimmer.

This site is from Michigan State University's Elementary Physics II class and details equipotential lines. The site displays maps and diagrams as well as formulas and rules for these types of lines.

What is power? Illustrated discussion of power including how it is measured and electrical power.

A teacher lesson plan is provided here. This page describes two activities in which the effect of multiple resistors on the current and overall resistance of both series and parallel circuits are investigated. Complete activity...
