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.
