Students calculate the resistance across a bank of resistors in a series, parallel and combined circuit. Using new vocabulary words, they define and describe them in a scientific manner. After stating Ohm's Law, they solve electrical...

Students are introduced to the topics of electric currents and resistance. In groups, they distinguish the difference between conventional and electron flows and state Ohm's Law for electrical components. They calculate the resistance of...

Not all energy sources are renewable, as learners investigate in this unit. Made up of six lessons that span a few weeks of instruction, the unit has learners examining US energy reserves and consumption, using data to draw conclusions...

This tutorial is devoted to an understanding of electric potential difference and its application to the movement of charge in electric circuits. Take the interactive quiz to assess your understanding.

In this interactive tutorial students will learn about electric potential and the principle of superposition. They will discover how superposition applies to electric fields and how electrostatic potential energy relates to electric...

This tutorial visits the concept of power. You will learn to develop new equations that express power in terms of current, electric potential difference and resistance.

This is a Java tutorial showing the simple voltaic (or galvanic) electrical cell, which is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

There are certain formulas in physics that are so powerful and so pervasive that they reach the state of popular knowledge. The predominant equation which pervades the study of electric circuits is often referred to as the Ohm's law...

An electron traveling through the wires and loads of the external circuit encounters resistance. In this tutorial, the concept of resistance is introduced. For an electron, the journey from terminal to terminal is not a direct route....

[Free Registration/Login may be required to access all resource tools.] This lesson looks at what voltage is and how to solve problems involving voltage. Includes a simulation for exploring how charges work in an electric field.

What four arrangements would result in the successful lighting of a lightbulb? And more importantly, what does each of the four arrangements have in common that would lead to an understanding of the two requirements of an electric...

[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...
