Ampacities of Insulated Conductors. The load current rating and the over current protection for conductor types shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG alumin
There are three main series of transistor codes used in the UK:The first letter B is for silicon, A is for germanium (rarely used now). The second letter indicates the type; for example C means low power audio frequency; D means high power audio frequency; F means low power high frequency.

Devices & Circuits
Zener diodes are used to maintain a fixed voltage. They are designed to 'breakdown' in a reliable and non-destructive way so that they can be used in reverse
Darlington Pair consists of two transistors connected together so that the amplified current from the first is amplified further by the second transistor.

|IGBT - Insulated Gate Bipolar Transistor|
The bipolar power transistor is a three layer NPN or PNP device within the working range, the collector current IC is a function of the base current IB,

Definitions regarding Electromagnetic waves
Some important definitions of terms used in electromagnetic waves.i.e wavelength multiplexing,fresnel reflection, optical dispersion, absorption, scattering, group velocity photon, polarization, wave length λ
When the alternating current passes through a wire than it sets up an electromagnetic field that propagate away from the wire.
