A short circuit occurs when a current flows through an electric circuit without resistance. If electrons flow without being impeded in some way, excess heat will be caused by the friction of these electrons moving in the conductive material. Too much heat will eventually damage the circuit, perhaps through fire or worse. Short circuits occur […]

The href attribute can be used with the hyperlink element <a> tag to identify exactly where we want that link to go, whether it is an internal link within the site itself or […]

Optical Telescopes
Optical Telescopes are able to collect significantly more light than the human eye, the larger they are the more light they are able to capture, which then forms and image of distant objects for the eye to see. When we turn a telescope to the night sky an optical telescope gathers and focuses light allowing […]
