electromagnetic wave - Wave taht consists of both electric and magnetic variation.
full wave rectifier - Rectifier that makes use of the full AC wave in both the positive and negative half cycles.
half wave rectifier - A diode rectifier that converts AC to pulsating DC by eliminating either the negative or the positive alternation of each input AC cycle.
horizontally polarized wave - Electromagnetic wave that has the electric field in the horizontal plane.
microwave - Band of very short wavelength radio waves within the UHF, SHF and EHF bands.

Audio
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


Alternating Current
Alternating Current (AC) It's common sense electrons can flow either forwards or backwards along a conductor. We learnt with DC that DC is when current flows only in one direction. Alternating curren

Signals
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
