Glossary
AC: Alternating current
AM: Amplitude modulation
Capacitor: It is an electrical component that stores electricity. It is composed of two small metal plates, and some electrolytic fluid. It is measured in Farads.
Capacitive Reactance: The phenomena that as the frequency of current increase, the resistance decreases.
Current: An electric current is a flow of electric charge.
DC: Direct current
FM: Frequency Modulation
Frequency: The number of times something oscillates in a single second. In the case of electronics, it is the rate at which an electron vibrates.
Impedance: Similar to resistance, it is a term to show electrical resistance.
Inductive Reactance: As the frequency increase through an inductor, the resistance increase.
Inductor: An electrical component that creates a magnetic field. It is used most electrical devices and is measured in Henrys.
Phases: Refers to the alignment of two sinusoidal waves, and the difference in their angle on the unit circle.
Period: Is the time in between each peak in a sinusoidal wave, and time is plotted on the x-axis. As the Frequency increase the period decrease.
Resistance: Is the amount of electrical reduction in current that is done.
Volt: A unit of energy equal to the energy acquired by an electron falling through a potential difference of one volt.
Watt: Is equal to the voltage multiplied by its current.
Wavelength: The distance between two peaks of a sinusoidal graph, with distance plotted on the x-axis.
