# AC real, reactive and apparent power
# Scope: Sinusoidal single-phase apparent, real and reactive power.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

voltage = 230 V
current = 2 A
phase = 30 deg

apparent := voltage*current [VA]
realPower := voltage*current*cos(phase) [W]
reactive := voltage*current*sin(phase) [V*A]

check real power budget: realPower <= 450 W

scenario alternative: voltage = 184 V
