Students learn about static electricity using terms such as friction, induction, and conduction. They also explain and illustrate the difference between alternating and direct current, and understand the relationship among voltage,...

Take a look inside a battery and change the voltage to see what goes on inside. Read the voltmeter as little stick people move the charges from one end of the battery to the other.

Build an intuitive understanding of current and voltage, and power.

Kid's learn more about the science of electricity. How its measured and generated.

Apart from the piezo generator, all of these generators are based on the same simple design, where magnets are rotated near to coils of wire (Faraday Induction). There is no coil switching so these are AC generators. On magnet movement,...

[Free Registration/Login may be required to access all resource tools.] Explains what electric current and voltage are and why electric current occurs.

Explains the design of two circuits that can flash an LED from a single 1.5V battery. A typical LED needs 2-3V to work properly and both these circuits include a voltage doubler to boost the voltage to drive the LED. Both circuits will...

In this unit students discover the meaning and some applications of electric potential, commonly known as voltage, and how it powers some simple circuits.

Using a voltage sensor, students will measure how much "electricity" is produced by the wind turbine that they design and build. Students will experiment with blade designs to see which one collects energy from the wind the most...

A rather mathematical explanation of a capacitor. Gives all the appropriate formulae, with many hotwords for further info.

[Free Registration/Login may be required to access all resource tools.] Discusses how an electric transformer works and step-up and step-down transformers.

[Free Registration/Login Required] Students can use this Flipchart to learn and apply Ohm's law to basic circuitry problems. Students are introduced to the relationship among voltage, current, and resistance, and then apply their newly...

Some basic concepts to introduce the electrical engineering course. Become familiar with engineering numbers and notation, and learn about the two most important electrical quantities: current and voltage.

Electrostatics is the study of forces between charges, as described by Coulomb's Law. We develop the concept of an electric field surrounding charges. We work through examples of the electric field near a line, and near a plane, and...

Investigate the nervous system by looking at nerve cells in this virtual lab. This lab exercise allows students to experience a virtual dissection of a leech to use electronic equipment to explore the electrical activity of nerve cells....

An electrical circuit simulation modeling the behavior of a voltage source attached in a series to a resistor and capacitor.

A simulation investigating a parallel-plate capacitor which is charged by connecting one plate to the positive end of a battery, and the other plate to the negative end. The battery sends electrons from one capacitor plate to the other...

Simulation demonstrating how a point charge, a dipole, or a quadrupole shows field vectors or voltage. Change the charge and see the electric field direction and magnitude, and then record the detector values using a built-in data...

Kids learn about Ohm's law in the science of electricity and physics including current, resistance, voltage, example problems, and V=IR.

Experience the photoelectric effect by choosing different light frequency, voltage, and metals to stop current from flowing in a circuit.

An impressive photo showing a high voltage discharge during a Tesla coil demonstration.

This photo looks up at the imposing structure of high voltage overhead powerlines. These structures are common all over the world as they have the important job of holding up the huge lengths of powerlines that carry electricity from the...

Circuit analysis is the process of finding all the currents and voltages in a network of connected components. We look at the basic elements used to build circuits, and find out what happens when elements are connected together into a...

Review how to find the equivalent resistance for resistors in parallel and series configurations. Recall the current and voltage properties of series and parallel configurations of resistors.
