ummm.. could anyone tell me what is the function of a transistor ? it switching device.. yeah? i get the base emitter collecter thing.. but they ask in the exam how do u define a transitor? as a current amplifier or summat?

The design of a transistor allows it to function as an amplifier or a switch. This is accomplished by using a small amount of electricity to control a gate on a much larger supply of electricity, much like turning a valve to control a supply of water.
Transistor terminalsTransistors are composed of three parts – a base, a collector, and an emitter. The base is the gate controller device for the larger electrical supply. The collector is the larger electrical supply, and the emitter is the outlet for that supply. By sending varying levels of current from the base, the amount of current flowing through the gate from the collector may be regulated. In this way, a very small amount of current may be used to control a large amount of current, as in an amplifier.
Hope that helps :)
