How does transistor amplify current

I want to know how do they what do they do. A current at the base turns on the transistor. Transistors are normally used as amplifiers. And other modes too A transistor can also amplify the voltage is sees on the base.

A transistor consists of three layers of a semiconductor material.

The transistor is said to be in emitter-follower mode for this to occur. Meaning of Transistor Amplification. Intake of Dairy Products to Get Pregnant With Twins. How can a transistor just amplify electric current from nothing. I have heard transistors are used in many electronic devices to amplify current such as in microphones which amplify the sound.

I'm trying to understand transistor amplification here.

What the laser does is add more photons of the same energy to the stream. I don't see how a transistor is amplifying anything. Electrons cause the flow of more electrons due to the way they interact with quantum transitions in the atoms of the 'amplifying medium'. The collector and emitter are hooked up to a completely separate power source.
