# Power and energy conversion
# Scope: Constant-power energy over a stated duration.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

power = 100 W
duration = 2 h

energy := power * duration [Wh]
joules := energy [J]

check energy budget: energy <= 250 Wh

scenario alternative: power = 80 W
