On the other hand the RMS describes which direct current delivers the same amount of power within the same time period.
Thus the easiest way to determine a quantitative measurement size is to use the average rectified value.
The average rectified value is mainly used to characterize alternating voltage and current.
[1] While conceptually similar to the root mean square (RMS), ARV will differ from it whenever a function's absolute value varies locally, as the former then increases disproportionately.
The difference is expressed by the form factor[2] This engineering-related article is a stub.
