On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Simple Transistor Tester This handy transistor tester allows you to quickly test the function of an NPN/PNP transistor, JFET or (V)MOSFET and identify the correct leads.

A bipolar junction transistor (BJT) has three regions, of which the emitter and the collector are made of the same type of semiconductor (‘n’ for npn and ‘p’ for pnp) but the base is of opposite type.

00 While experimenting with electronic circuits, it will often be necessary to rap- idly test bipolar transistors and FETs before they are fitted in the circuit, or when they have been removed from ...
