AC (Alternating Current)

A few important characteristics of an AC Signal:

Time Period

How much time passes during one cycle of the signal (until it reaches the same point it started twice)

Frequency

How many cycles the signal completes in a specified time frame.

Amplitute

The maximum voltage of the signal compared to 0

Peak-Peak Voltage

The difference between the highest and lowest peak.

Root Mean Square Values

This helps calculating the current an equivalent DC Signal would need to provide the same amount of power.

V_{RMS} = 0.7 * V_{PEAK} &&\\
V_{PEAK} = 1.4 * V_{RMS}
