Build circuits with batteries, resistors, ideal and non-Ohmic light bulbs, fuses, and switches. Determine if everyday objects are conductors or insulators, and take measurements with an ammeter and voltmeter.

This is an interactive sim. It changes as you play with it.

Explore and experiment with interactive circuit simulations to learn about batteries, resistors, light bulbs, switches, and electrical concepts like Ohm's law.

Build circuits with batteries, resistors, light bulbs, and switches. Determine if everyday objects are conductors or insulators, and take measurements with a lifelike ammeter and voltmeter.
