SUMMARY
The length of the shunt was calculated using the formula l = AR/ρ, where A is the cross-sectional area, R is the resistance, and ρ is the resistivity of copper. Given a cross-sectional area of 25 cm² and a resistance of 0.5 μΩ, the calculated length of the shunt is 7.4 mm. The resistivity of copper used in the calculation is 1.7 x 10-8 Ω·m. The discussion highlights the importance of unit consistency in calculations.
