Question

Current density of the EP process generally varies between which of the following values?

(a) 0.0001 – 0.001 A/cm^2

(b) 0.005 – 1.8 A/cm^2

(c) 1.9 – 2.532 A/cm^2

(d) 3.523 – 4.23 A/cm^2

This question was posed to me in quiz.

My question is from EP-Process Parameters topic in chapter Chemical Processes of Advanced Machining

Answer 1

The correct answer is (b) 0.005 – 1.8 A/cm^2

The explanation: Generally current density value used in EP process vary between 0.005 – 1.8 A/cm^2.
