(a) 1 to 60 A/cm^2

(b) 60 to 120 A/cm^2

(c) 120 to 240 A/cm^2

(d) 240 to 480 A/cm^2

This question was addressed to me in homework.

My query is from ECG-Material Removal Rate in section Hybrid Electrochemical Processes of Advanced Machining

Answer 1

The correct choice is (c) 120 to 240 A/cm^2

The explanation: The values of current densities range from 120 to 240 A/cm^2.
