Problem
A steel panel is plated with chromium using a constant current. If all other conditions (temperature, electrolyte concentration, and exposed area) remain unchanged, doubling the time that the current is applied will have what effect on the average thickness of the chromium layer?
(a) The thickness will become four times larger.
(b) The thickness will be halved.
(c) The thickness will double.
(d) The thickness will remain unchanged.
