From the graph will have a value that is not of course so it will start reading a value from 5 seconds and stores a value from 5-20 seconds since then bring up the average collected. The average value of which is approximately 20N-30N.
From the graph it is unpredictable, so you start reading from the second, and so on five charges ranging from 5-20 seconds, then bring the collected average. The average value of approximately 20N-30N.
From the graph will be the unstable so will begin to read the value from the second 5 etc. and collect value since the moment 5-20 the value the average. The value of the average was about 20N-30N.
