It's November now. Two months into class and you still don't know?

What do you find when you Google "transistor amplifier"?

Google on transistor wiki

The first sentence says:"
A transistor is a semiconductor device used to amplify and switch
electronic signals and power".

In fact it is a current amplifier.

That depends on the type of transistor and also on the circuit topology.

Yes, it's a "current amplifier," which, depending on the circuit
configuration, can make a voltage amplifier, a current amplifier
(either of which could be described as "electronic signals") and/or
a power amplifier.

And don't forget, that's Wiki, not Elementary Electronics 101. ;-)

Hope This Helps!
