# Current-sense resistor and amplifier # Scope: Shunt and ideal amplifier current measurement. # Status: illustrative worked example; engineering review pending. # Inputs are example values. Checks are editable example requirements, not standards. current = 5 A shunt = 0.01 ohm gain = 20 shuntDrop := current*shunt [V] output := shuntDrop*gain [V] loss := current^2*shunt [W] check shunt power budget: loss <= 0.5 W scenario alternative: current = 4 A
