Diodes Diodes are one of the most common semiconductor devices. As we know from the last page, both N and P type silicon conduct electricity. The conductivity (or resistance) of both is by how doped

Static Electricity Most of us have experienced or even played with static electricity at one time or another. So in this page well explain what it is and have a play with it. Static electricity is

Quick Voltage Dropper If you fliped through our section on semiconductors you might have noticed that silicon diodes need at least 0.6 volts to work and reduce the voltage by 0.6 volts. So we can tak

Unijunction Transistor The unijunction transistor (UJT) works like a switch. It doesn't amplify the voltage, it just lets current through or not depending on the in input voltage. Irrespective

Bipolar Transistors One of the two types of transistors are bipolar transistors. From Diodes we learnt about PN junctions. Now with bipolar transistors we add another layer to make it PNP or NPN depe
