When the electrolyte flow is low, what happens to the current efficiency?

(a) Increases

(b) Decreases

(c) Remains same

(d) Increase and then decrease

The question was posed to me by my college professor while I was bunking the class.

I need to ask this question from ECM-Process Characteristics in division Electrochemical Processes of Advanced Machining

Correct choice is (b) Decreases

For explanation I would say: In ECM, if the electrolyte flow is low, current efficiency is reduced due to the accumulation of machining products within the gap.
