    The Ben Heck Show


    In today's Episode Karen discusses transistors. Rather than using a physical, mechanical switch, a transistor can act as an electronic switch, using signals to turn it on or off.  She'll go over what they are, how they work, and some types of transistors.  She'll cover Bipololar junction transistors (BJT), NPN transistors, PNP transistors, and darlington transistors.
