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....

[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...

Find out how to determine resistance using Ohm's Law.

See how this application of Ohm's Law leads to a formula for the total of parallel resistances.

A general summary of electrical resistance including a comparison of AC and DC current.

Use the tutorial to find the total resistance for resistors in a series circuit.

Use the formula for the parallel resistors to calculate the total resistance in series-parallel circuits.

See how Ohm's Law can tell us that the voltage across resistors will depend on that current value I and each R-value.

Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.

In this interactive, students can explore how current, voltage, and resistance are related in a model showing the flow of electrons in an electric circuit. They will learn about Ohm's law and how other forms of energy can be made from...

In this interactive tutorial, students will analyze series circuits and parallel circuits along with complex circuits composed of elements in series and parallel. Learners will use schematics to help them understand these circuits....

Learners investigate current electricity. Some topics examined are voltage law, Ohm?s law, and electric resistance. The resource includes example problems with solutions and a chapter quiz.

In the everyday electrical devices we use - calculators, remote controls and cell phones - a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use a battery,...

Provides a long list of physics formulas for easy reference.

In this science fair project, use a calorimeter with an attached heating element to measure how water responds to added thermal energy.
