# Wheatstone bridge and sensor output
# Scope: Ideal Wheatstone bridge differential output.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

excitation = 5 V
rA = 1000 ohm
rB = 1010 ohm
rC = 1000 ohm
rD = 1000 ohm

output := excitation*(rB/(rA+rB)-rD/(rC+rD)) [mV]

check bridge output budget: abs(output) <= 20 mV

scenario alternative: excitation = 4 V
