What happens when you release the pushbutton switch? Which wire on the transistor is the trigger that allows current to flow? __________ Describe what each wire does Collector Base Emitter If you change the 3.3K Ohm resistor, what changes?________ ____________________ Use an ammeter to measure how much current is flowing before and after you change the 3.3K Ohm resistor. Why would this be called an amplifier? What is being amplified? An increase of current through the base emitter will result in a larger current through which side of the circuit? Look up the term transistor online. Describe what it is.
