Then I guess you shouldn't estimate electrical input power from V and Iav.
You should estimate it from V and R?


It is important to remember that there are other kinds of power besides
electrical power. In the end if enough heat is produced the most effective
way of converting the heat into electrical power, might be through a boiler
and a steam driven turbine.
