Document Summary
The transistor frank h. rockett largely determines the size of the apparatus in which they are used. American electrical engineer named lee de forest discovered that if an electrified wire grid was placed across the path of a stream of electrons in a vacuum tube, the flow of electrons could be controlled in interesting ways. The transistor is a device that is used as a method of controlling electrons in a. Transistors reduce the complicated, delicate tube to a simple rig consisting. It does not need to heat up and so it goes to work instantly. It operates on a tiny amount of power about one tenth used by flashlight bulbs. It can be made vanishingly small about the size of the eraser on a pencil. The size of vacuum tubes is an important consideration in electronics, for it. Promises to reduce electronic equipment in general to an even smaller scale.
