संकल्पना:

विद्युत रासायनिक मशीनिंग (ECM) में आवश्यक धारा इस प्रकार दी गई है:

\( I = \frac{\text{MRR} \times \rho \times Z \times F}{M \times 60} \)

दिया गया है:

\( \text{MRR} = 5~\text{cm}^3/\text{min},~\rho = 7.8~\text{g/cm}^3,~Z = 2,~M = 56,~F = 96500~\text{C} \)

गणना:

\( I = \frac{5 \times 7.8 \times 2 \times 96500}{56 \times 60} = \frac{7524000}{3360} \approx 2240~\text{A} \)
