hole - A gap left in the covalent bond when a valence electron gains sufficient energy to jump to the conduction band

Semiconductors
Semiconductors Semiconductors are quite possible one of the most important things in the modern world. The are made from crystals and can act as conductors or insulators in different circumstances.


Diodes
Diodes Diodes are one of the most common semiconductor devices. As we know from the last page, both N and P type silicon conduct electricity. The conductivity (or resistance) of both is by how doped

Static
Static Electricity Most of us have experienced or even played with static electricity at one time or another. So in this page well explain what it is and have a play with it. Static electricity is
