battery

For the teacher planning a lesson or for the student preparing for a project or presentation. This page describes an activity in which parallel and series circuits are constructed using batteries and bulbs. Complete activity directions...

With only minor changes to its original 1866 design, the Leclanche cell evolved into modern alkaline batteries and the most popular household battery to date.

In the everyday electrical devices we use - calculators, remote controls and cell phones - a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use a battery,...

Learn how to create electricity and your own electrical gadgets! Site provides users with information on how to make a battery, flashlight, buzzer an electric motor.

You will learn about a voltaic battery and to see if it's powerful enough to light up a light bulb

This website lists and describes different types of "Intentional interference with person or property": battery, offensive contact, false imprisonment, abuse of process, and breach of contract.

English mathematician Peter Barlow devised an instrument in 1822 that built on advances from earlier in the century (including the invention the battery) to create a very early kind of electric motor.

Italian scientist Alessandro Volta was the first to recognize key principles of electrochemistry, and applied those principles to the creation of the first battery, a simple tool which came to be known as the voltaic pile.

Learn how Alessandro Volta became a pioneer of electricity and power, and who is credited as the inventor of the electrical battery and the discoverer of methane.

Students investigate motors and electromagnets as they construct their own simple electric motors using batteries, magnets, paper clips and wire.

Find the terminal voltage of a battery with significant internal resistance. Determine the power of one of the external components for the circuit.

Discover what it is about citrus fruits that enable them to conduct electricity, then make your own citrus fruit battery using the instructions given here.

Review the components of a circuit and their symbols such as battery, resistor, and switch. Analyze how the power of a resistor is related to the current and electric potential difference across the resistor.

Play with resistors, light bulbs, wires, switches, a battery, voltmeters, and ammeters in this interactive circuit simulation.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This one...
