A site dedicated to help students prepare for the AP Physics B test. This specific site reviews electrostatics including electric charges, Coulomb's law, static electricity, electric fields, electric potential, and electrostatic...

How do objects become grounded? Probe into the science behind "grounding" objects by removing an electric charge. Explore the Charge Interactive and test understanding with the three follow-up questions.

In this interactive students will explore the strength of an electric field in the space surrounding a source charge. It is related directly to the quantity of charge on the source charge and inversely to the distance from the source...

[Free Registration/Login may be required to access all resource tools.] Explains what electric current and voltage are and why electric current occurs.

Electrical force between two electrically charged objects is inversely related to the distance between the two objects. Investigate why this becomes the inverse square law of physics. Engage in the Coulomb's Law interactive and check...

This unit teaches students the foundations of electrical circuits and introduces them to their simplest components. Covers series and parallel circuits, Kirchhoff's Rules, Ohm's Law, RC circuits, resistivity, and capacitance.

Students learn about static electricity using terms such as friction, induction, and conduction. They also explain and illustrate the difference between alternating and direct current, and understand the relationship among voltage,...

In this unit students discover the meaning and some applications of electric potential, commonly known as voltage, and how it powers some simple circuits.

Explore what an electric field is and how electric fields interact with this module. Module includes a video, interactive activity, and review questions.

[Free Registration/Login may be required to access all resource tools.] Students learn which subatomic particles contribute to static electricity, and determine the charge of an object based on what particles it has gained or lost.

In this tutorial, preconceived ideas regarding the nature of charge flow and the role of a battery in a circuit are addressed. In many instances, these preconceived notions about charge flow and batteries are incorrect ideas and are...
