A transistor is a semiconductor device used to amplify or switch electrical signals and power<\/b>. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\u03b2 (beta), the gain or amplification factor of a transistor, normally is given when solving a circuit equation.
\u03b2 = \u00a0I C<\/sub>\u00a0\u00a0\/\u00a0 I B<\/sub>\u00a0
\u03b2 =\u00a0 ( I E<\/sub>\u00a0\u00a0\/\u00a0 I B<\/sub> )\u00a0 – 1<\/p>

It uses a small base current to trigger a large collector current on the NPN or large emitter current on PNP.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
