‪Circuit Construction Kit: DC - Virtual Lab‬.

Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET …

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.

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

Observe the current value in the yellow box in the circuit and the two graphs on the right. The current will increase as more photoelectrons are produced over time.

Before coming to lab and working with some real circuits, here’s a chance to spend some time with simulated circuits. This will introduce you to the use of voltmeters and ammeters within a …

‪Circuit Construction Kit: AC - Virtual Lab‬.

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

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 …

Build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and inspect them using lab instruments such as voltmeters and ammeters.
