[Free Registration/Login Required] Learn about the analysis of parallel circuits in the context of a realistic household circuit using our interactive simulation. A PDF worksheet and a video tutorial are also available. [3:24]

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

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...

Explains the design of two circuits that can flash an LED from a single 1.5V battery. A typical LED needs 2-3V to work properly and both these circuits include a voltage doubler to boost the voltage to drive the LED. Both circuits will...

Students learn about capacitors and inductors and their role in electrical circuits.

Students are introduced to the idea of electrical energy. They learn about the relationships between charge, voltage, current and resistance. They discover that electrical energy is the form of energy that powers most of their household...

A teacher lesson plan which could be easily converted into an idea for a student project or presentation. This page describes an activity in which the water-electricity analogy is used to investigate the relationship between current,...

Magnetic shunts are often used to adjust the amount of flux in the magnetic circuits found in most electrical motors. (Java tutorial)

This investigation has students investigating and measuring the decay of batteries as their electric charges are used up in circuits.

Alternating current behaves differently, depending on what components are in a circuit.

Looking for some more explanantion on a topic covered in physics class? This site contains videos that explore some physics concepts. Videos are broken down by topics. Some videos also give examples on how to solve problems.

Gross. What is that in the toilet? But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair...

Following a PowerPoint lecture, students will participate in a laboratory investigation where they dissect a disposable camera.

This site contains information about becoming an Electrician in New Zealand. While some of the information is specific to New Zealand, there is also data that is uniform to the career.

Find out how the SPARKS DMM can measure AC voltage and current.

At this site from Georgia State University parallel and series connections of resistors are explained and illustrated. Equations for computing the overal voltage, current, and resistance of such circuits are given and explained.
