How does a transistor amplify current? A transistor consists of three layers of a semiconductor material. Those layers are capable of carrying a current. Transistors are devices that can amplify a signal in a circuit. It is normally made of germanium or silicon layers.

Do you have this one? If you do not have it. Look: A lot of Power supply circuit Build the 9V mini amplifier This circuit is a small size you can assemble them on the breadboard. Make a layout diagram first which very nearly follows the schematic diagram before attempting any soldering. With care you will find you will not have to cut any of the universal PCB Board tracks and most the parts will fit neatly onto the board as they all 0.
For my son plan will build it on wood board or hard paper it also saving money and funny. When you complete soldering, Next, connect the battery via a milli-ammeter to check, that the current is within 30mA and most probably is mA with no input signal.
You may like to trace through the amplifier with the signal tracer project. Obviously, all the step cannot provide the good amplifier, since a transistor has a gain of at least 20 times, and sometimes an in-circuit gain of Thus, this gain of amplifier about 20 x 20 x 20 or 8, times!
But this is not so. If the input about mV, the amplifier needs to provide a gain of about 40 to 80 times. Your signal tracer will indicate which transistor is providing this gain. See for yourself. In all, these combined 4 transistors projects should give you hours of fun.
