WebTransistors also work as switches. A small electric current flowing through one part of a transistor can make a much larger current flow through the other part. This is how all computer chips work. For instance, a memory chip includes hundreds of transistors, each of which can be switched on or off individually. WebTransistors rely on semiconductors to work their magic. A semiconductor is a material that's not quite a pure conductor (like copper wire) but also not an insulator (like air). The conductivity of a semiconductor -- how easily it allows electrons to flow -- depends on variables like temperature or the presence of more or less electrons.
