$begingroup$ You need to log that measurement. The easiest way, as Elliot Alderson said, is to use an oscilloscope. Measure over a series resistor for a duration of 1 minute, work out the average drop over the course of a minute and use Ohm''s Law to give you the current. Then that gives you the total current for a cycle.
