# Why is dissipation of electric power as heat minimized? [closed]

For a given electric circuit, currents and voltages are distributed to minimize the total power dissipated as heat. It seems that, there is some kind of action which is stationary.

What is the reason for this?

• The currents and voltages in simple circuits consisting of ohmic devices are such that ohm's law is obeyed. We calculate the energy dissipated as heat using ohm's law. – Yashas Mar 24 '17 at 12:11
• -1. Unclear. Please provide a reference and context for the statement in your first sentence. Please also explain what your 2nd sentence means. – sammy gerbil Mar 24 '17 at 17:41
