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

What do you find when you Google "transistor amplifier"? -- www.wescottdesign.com

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! Rich
