## DC Circuit Builder

Design and build circuits on your phone or tablet for free!

"So that's how parallel circuits work!" - Physics student

From Nerd Island Studios, LLC the creators of the top-rated "Step2Step Physics - Mechanics" for the iPad, comes an easy-to-use DC circuit builder:

• Build and test series, parallel, and compound circuits

• Visible charges flow through the circuit components

• Voltmeters and ammeters behave like the real thing

• Voltages are shown right on the circuit nodes

• Bulbs glow brighter according to the amount of power they are dissipating

Tested by high school teachers and students, DC Circuit Builder meets the need for a simple classroom tool to show students the basics of current and voltage, as well as the proper use of voltmeters and ammeters.

## Fun With Resistors

A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. A resistor is perhaps the most common building block used in circuits. This tool is used to decode information for color banded axial lead resistors. Select the number of bands, then their colors to determine the value and tolerance of the resistors.
