Transistors

Transistor

You cannot avoids them in electronic! Transistor offers many help when you need to power anything bigger than a LED. Transistor are helful to swich higher power, higher current or higher voltage source to a load. Some of them are specialized for commutate power, other to amplifies signal and some to work at high frequency. Sometime transistors are bit difficult or obscur to handle but they can really handle strong power.
