Is this a home work problem? We are generally not keen on doing peoples homework for them. But if you are stuck on a particular point people will gladly help out.
There are hundreds of tutorials around the net about using transistors. See links given above for example.
It kind of depends on your application. What is it you actually need to do?
The newskool generation understands dub. It wobbles more. They have less De-bouncing with their 'tranistor'.
They probably just need a harder bias 'resister' on their gate.

A simple google search would bring up the information you need.

The collector value would be based on your voltage, which you did not provide.

Did she have the capacity? Could she be induced? Or was she purely resistive?
