An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view....

The invention of the light bulb quickly created the need to track people's electricity usage. In 1872, Samuel Gardiner built the first simple power meter: a lamp with an attached clock that recorded the time the light was on.

Students will work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. It analyzes Ohm's Law, power, parallel and series circuits, and ways to measure voltage and current.
