This is a Java tutorial showing the simple voltaic (or galvanic) electrical cell, which is the most basic type of "wet" cell and demonstrates the fundamental chemistry behind batteries.

Find out about the usage of electricity. and how it affects modern energy use.

Brief illustrated explanation of how hybrid electric vehicles (HEVs) work.

Presents a general overview of fuel cells including what is a fuel cell, how do they work, and the different types.

Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an...

William Gilbert was an English physician and natural philosopher who wrote a six-volume treatise that compiled all of the information regarding magnetism and electricity known at the time. The work included descriptions of many of...

Joseph John Thomson, better known as J. J. Thomson, was a British physicist who first theorized and offered experimental evidence that the atom was a divisible entity rather than the basic unit of matter, as was widely believed at the...

By building a basic thermostat, students will explore basic circuitry and electricity. The thermostat built out of a breadboard, temperature sensor chip, amplifier, and battery creates a linear relationship between temperature of the...

It may look like a simple black blob, but an oil drop is in fact a phenomenally complex mix of immense molecules called hydrocarbons. Using a type of mass spectrometry called FT-ICR, scientists can analyze oil and other macromolecules...

In this electronics science fair project, students will make a simple dimmer switch and investigate the relationship between the resistance in the circuit and the amount of light produced. The Science Buddies project ideas are set up...
