DFE: Cathodic Protection level 1


Right now, i still at Royale Bintang. Learn CP level 1. Just now, the instructor ask pretty simple question. Electrical current flow from where to where?

If i remember correctly, during my school days, the physics teacher taught me current flow from positive to negative. I couldnt disagree no more.

At U, lecturer explains that current flow from negative to positive. Reason why is that electron flows the same way. And yes, you shouldnt argue with your lecturer. Hehe.

Now, the instructor explained the true fact. The answer is, IT DEPENDS. It still confusing to me. Maybe in next posts i'll explained. I need Google this one. Or Wiki?
