# RL current transient
# Scope: Ideal series RL current step at one time.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

voltage = 12 V
resistance = 10 ohm
inductance = 100 mH
time = 20 ms

timeConstant := inductance/resistance [s]
current := voltage/resistance*(1-exp(-time/timeConstant)) [A]

check current budget: current <= 1.5 A

scenario alternative: voltage = 9.6 V
