As an amplifier, it can take in a small current and amplify it to produce a much bigger output current. One of the examples of this could be in a microphone connected to a loudspeaker, where the mic takes in a small sound input and amplifies it to produce a much louder sound when it comes out via the loudspeaker.
Similarly, as a switch, it can take a small current input and use it to allow a much larger current to flow by activating the new current flow.
This is what a transistor looks like:

The following is how ...
