Best Answer

A transistor is a miniature electronic semiconductor device with 3 terminals that uses minute particles called electrons to control the movement of current. The 3 terminals are the emitter or input, the collector or output, and the base or controller. when a small voltage is applied to the base, the electrons from the emitter are released and travels to the collector causing current to flow. This is the 'on' state of the transistor. When voltage is increased, the base will also increase allowing more electrons to flow. If voltage supply is stopped, the base will close and no electron will move and the transistor is now on its 'off' state.

Why is a transistor a NOT gate?

A normal configuration for a BJT is Class A Common Emitter. In this configuration, the BJT operates as an inverting amplifier. Driven into saturation, it is a inverting switch, hence the designation NOT gate.Transistor can act as a gate. But its not a gate. In BJT(Bipolar Junction Transister) type transisters there are two P-N juntions. That means if we need we can use it as a NOT gate. Actually gate ICs (Intergrated circuits) are also build using transistors. (Example : TTL(transister-transister logic))
