Experiment with an electronics kit! Build circuits with batteries, resistors, ideal and non-Ohmic light bulbs, fuses, and switches. Build circuits with AC voltage sources, batteries, resistors, capacitors, inductors, fuses, and switches. Take measurements with a lifelike ammeter and voltmeter and graph the current and voltage as a function of time. View the circuit as a schematic diagram or switch to a lifelike view.

Explore how a capacitor works! Change the size of the plates and the distance between them. Change the voltage and see charges build up on the plates. View the electric field, and measure the voltage. Connect a charged capacitor to a light bulb and observe a discharging RC circuit.
