"Why Not Alternate Current ?"
Why Alternate current is not used in Plating process what happens if we apply? If any one have seen this question please clear my doubt...RamaKrishna Adivistnu

Suppose you put two electrodes into a conductive solution, one of them connected to each end of this alternating current supply. Which of the two electrodes would you expect to dissolve into the solution to provide the plating metal, and which of the two would you expect to become plated with this dissolved metal?

Applying AC bias in electroplating is pretty much similar to trying to walk forward with one step ahead and the other backward....do you think you would be able to travel any distance? In electroplating process, you are providing electrons for metal reduction in a particular direction. AC bias would not do so constantly because the direction of flow of electron changes....now relate to the example of walking! hope you get the hint:)Ashish
