# Via-array current sharing screening
# Scope: Identical vias share DC current equally; mutual thermal effects omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

current = 5 A
count = 4
singleResistance = 0.001 ohm

perVia := current/count [A]
equivalent := singleResistance/count [ohm]
loss := current^2*equivalent [W]

check per via current budget example: perVia <= 1.5 A

scenario alternative: current = 4 A
