# Complex AC impedance
# Scope: Series RLC impedance magnitude at supplied frequency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

resistance = 100 ohm
inductance = 10 mH
capacitance = 1 uF
frequency = 1000 Hz
voltage = 10 V

reactance := 2*pi*frequency*inductance-1/(2*pi*frequency*capacitance) [ohm]
magnitude := sqrt(resistance^2+reactance^2) [ohm]
current := voltage/magnitude [A]

check current budget: current <= 0.1 A

scenario alternative: resistance = 80 ohm
