Uses of transistor

Answer 1

Radios, Televisions & Computers.

Answer 2

If your question is about kinds of transistors, then the kinds include bipolar NPN transistors, bipolar PNP transistors, point-contact transistors (the first kind ever made, but obsolete now), field effect transistors (FET). The FETs are the kind used in modern silicon chips and there are variants of them such as the classic planar FET and the very recent "fin FET" or 3D transistor. There are transistors made of crystalline silicon, of amorphous or semicrystaline silicon (like in your LCD screen), of Gallium Arsenide, of plastic, of carbon nanotubes, and various other materials. The basic requirement is that the material should be a semiconductor, a material having an energy barrier that electrons must be lifted to become conductive (as opposed to metals which are conductive without a barrier, and insulators which are all barrier and no conductive state).

If your question is about examples of things which use transistors, then you can include all forms of calculator and computer chip, radios, modern power controls, LCD screens, AMOLED screens, various kinds of sensors including the CMOS chips in cameras, and many kinds of electrical switch.
