# Series and parallel resistance
# Scope: Two resistors in series and parallel; ideal components.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

resistorA = 1000 ohm
resistorB = 2000 ohm
voltage = 12 V

series := resistorA+resistorB [ohm]
parallel := resistorA*resistorB/(resistorA+resistorB) [ohm]
parallelPower := voltage^2/parallel [W]

check parallel power budget: parallelPower <= 0.25 W

scenario alternative: resistorA = 800 ohm
