Research the location of land mines by animals and technological methods. Use a metallic probe to uncover the location of an electric-circuit target (representing a buried land mine) without setting off the "bomb".

Create your own simple electric circuit. Using simple supplies build your own battery and investigate conductivity. You can also construct a crossword puzzle with electrical vocabulary words.

Using your knowledge of electricity, learn how to make a 'magic' wand like Harry Potter's that will light up on your command.

[Free Registration/Login Required] Learn about how capacitors are used in circuits to create transient events such as the flash of a light bulb using this interactive simulation. A PDF worksheet and a video tutorial are also available....

Find out how the current in a circuit can be impeded by three types of circuit components.

Explains what an LCR meter is and how it is used to measure the inductance, capacitance, and resistance of a circuit. Lists the different parameters of a circuit that it measures, describes two types of LCR meters, and gives definitions...

Practice identifying the correct placement of voltmeters and ammeters to measure an unknown circuit or electric potential difference for a circuit.

This investigation has students examining how electric and magnetic charges are related. They will look at how an electric current is affected by the proximity of a magnet.

Explains the design of circuits that can be used to multiply and rectify AC voltages, e.g., to increase voltage in order to light an LED more effectively and get a brighter light from it.

Oscillators are a type of circuit found in many types of electronic equipment, including clocks, radios and computers. (Java tutorial)

Determine the voltage of the battery based on the colors of the resistor and the current in the circuit.

The voltage in AC circuits oscillates at a rate known as the frequency. With an oscilloscope, see and measure the length of time between signals, and calculate the frequency of an AC signal.

This tutorial illustrates why adding bulbs to a circuit makes all the bulbs dimmer.

This site contains a straightforward definition of resonance in an electrical circuit.

This simulation shows a simple circuit consisting of an AC voltage source and, depending on the button selected, a resistor, a capacitor or a coil.

This simulation is about an oscillatory electromagnetic circuit formed by a capacitor and an inductor.
