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...

[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...

Use this tutorial to find the voltage in an electrical current with Ohm's Law.

Learn how to measure the electrical current using Ohm's Law.

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

The instructional activity will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of...

We solve a circuit by direct application of the fundamental laws: Apply element laws (Ohm's Law and the like) plus Kirchhoff's Laws to solve for the currents and voltages of a circuit.

Students are introduced to several key concepts of electronic circuits. They learn about some of the physics behind circuits, the key components in a circuit and their pervasiveness in our homes and everyday lives. Students learn about...

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.

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

Use Ohm's Law to calculate the current in parallel circuits.

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

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 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,...

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

We are surrounded everyday by circuits that utilize "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are made of many simpler parallel and series circuits. In this hands-on activity, students build...

Build your own windmill and see how the wind can be converted into energy to produce electricity. This science fair project should help you understand the use of wind as a source of alternative energy. The Science Buddies project ideas...

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

Everyday we are surrounded by circuits that use "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are composed of many simpler parallel and series circuits. During this activity, students build a simple...
