Question: Which following expression is used to find the corrosion rate from current density of a corroding specimen?
Options
A : W/At = [(I ? am) / (n ? F)]
B : W/At = [(I ? am) / (n ? d ? F)]
C : W/At = [534 ? (I ? am) / (n ? F)]
D : W/At = [(I ? am) / (n ? F)] and W/At = [(I ? am) / (d ? n ? F)]
