    guys can you help me..my cousin need a schematic and the flow of a simple FET circuits using a breadboard, but his classmate chosen the switch first now he need another simple FET circuits that can be build on the breadbord, I hope you can help my cousin.:)

    How about a form of emitter folower amplifier. With a jfet it's called a source follower. Power supply, input coupling capacitor, jfet, source resistor that will pass the idle current and have a voltage drop in the right range for the idle current. Three parts and you have a current amplifier or impedance matching circuit with a gain of thousands.
