You calculate it using S = (G * Ig) / (I - Ig), where G is galvanometer resistance, Ig its full-scale current, and I the desired ammeter range. But honestly, my main memory is of sweating in the school lab, trying to get the metre bridge to balance while my partner kept shouting the wrong readings. The real "shunt" in my life is how I divert my physics study time to calculate fertilizer dilution rates for the greenhouse instead. These formulas feel less practical than figuring out how much water the pineapples need before the next rain fails.
