ENERGY MEASURE WITH AN OSILOSCOPE

Hello friends. I almost became sure that we can measure of a Electrical wawe pulse''s spent energy with multiply Voltage and Current and take the result's integral with Osiloscope MATH function . I am working for a special experiment shown at picture. In the experiment we are giving DC current for a very short time (about 100-200 ms) and measuring 1- How much energy TOTAL spent ? 2-How much energy spent for COIL HEAT LOSSES? ( COIL'S resistance is 1 ohm ) For second question i multiplied current x current and i accepted the result wawe as a power wave again like first question's answer (because R=1 ohm and I x I = I x I x 1(R) = I.V) then i took the integral with scope again for energy measuring 1-..DO YOU SEE ANY MISTAKE about circuit or measuring way ? 2- Have you got easier way to measure these?

Kudos to you! You're very observant!
Although the link submitted below indicates current spikes the principle is the same! A very elegant solution has been given by a fellow member of this site.

The formed waves are here .Blue is for Voltage and Yellow is for current

Thanks for giving details.Yes it is generally similar but the circuit is different. Also i am especially asking for coil heat losses and how can we meausure it with scope
