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

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

Audio Components Audio components convert sound waves into currents and currents into sounds. Devices that convert sound waves to electrical current are normally know as microphones and devices that

Signals Once your circuits get more complex they will wan to communicate to other devices or to store information or to manipulate information. In electronics this is done with waves, pulses and sign

Electrical Circuits An electrical circuit is anything that allows current to flow, from a bulb attached to a battery to a desktop calculator. A simple circuit The most basic circuit you can get i
