The Main Idea

Alternating current is a varying current driven by varying voltages. This means the current is constantly changing (in both magnitude and direction) as a function of time. This is opposed by Direct Current, in which the current is constant and non-varying in either direction or magnitude.

Alternating current powers most appliances in residential and commercial areas. The wall outlets found in homes are connected to alternating current circuits. Alternating current is the predominant power source for most residential areas in order to efficiently and easily convert high AC voltages (straight from the power plant) to lower AC voltages (used in residential areas by appliances). Until recently, conversion from high DC voltages to low DC voltages was quite difficult and inefficient.

Alternating current is typically found in a sine wave function pattern.

A Mathematical Model

What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.
