Learn anything you ever wanted to know and more about electrical circuits here. Complete with in-depth explanations and detailed diagrams.

When there is a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever...

By building a basic thermostat, students will explore basic circuitry and electricity. The thermostat built out of a breadboard, temperature sensor chip, amplifier, and battery creates a linear relationship between temperature of the...

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...

Learners learn that charge movement through a circuit depends on the resistance and arrangement of the circuit components. In a hands-on activity, students build and investigate the characteristics of series circuits. In another...

A useful list of electrical symbols that are used in schematic diagrams. Each symbol is accompanied by its name and a caption stating its function.

Lesson focuses on how switches control the flow of electricity. Learners are posed with the challenge of designing and building a simple switch into an electric circuit.

Access Excellence offers detailed information, including diagrams and photos, about the anatomy of the heart and its central role in the circulatory system.

Students will work in small groups to design at least one complete circuit using multiple materials. They will record their observations of how they created an electrical circuit using diagrams and notes in their journals. Using a...

Explains what an LCR meter is and how it is used to measure the inductance, capacitance, and resistance of a circuit. Lists the different parameters of a circuit that it measures, describes two types of LCR meters, and gives definitions...

In this inquiry, students will attempt to build an electrolytic cell which will cause a bulb to turn on then diagram the set-up. Included in this lab, students will experience voltage, solve a problem using the Nernst equation, and...

Introduction to the Chinese postman problem with diagrams.
