Basic Electronics Notes

Energy Bands

When no of atoms is combining then the whole energy levels are dividing in sub energy levels and become overlapped.

Work Power & Energy

What is work, Power & Energy. Thermal efficiency, Joules Law, Heating effect of current, Horse Power

Transistor codes

There are three main series of transistor codes used in the UK:Codes beginning with B (or A), Codes beginning with TIP, Codes beginning with 2N


Transistor is an three layer PNP or NPN semiconductor device with two junctions. Transistor is made from semiconductor materials


A transformer is an electrical device used to change the value of an alternating voltage. transformers are widely used in electrical work.
