Question

In copper plating, a current of 0.54 is allowed for acathode area of 100cm2. If this current is maintained constant for 100 minutes, determine the thickness of the cooper deposited

Answer 1

Explanation:

m = Itz

density = massarea x thickness

Density = ItzA×h

104 = 0.5×100×60×0.003100×h

h = 9 x 10-6mm
