In past I talked about same topic in DCLocator(Part-I) & DCLocator(Part-II) posts. That time I came to that conclusion based on what I read in some blogs and my own experimeniting. The posts are not having any pictures or anything that can make my readers understand this concept clearly. It is completely a text rambling which people might feel boared to read it unless they have a urgent need.
I recently came across a video that explains the same DC locator process in a much pictorial way. I felt this is very useful for people to understand DClocator process to some level.
Hence making this post to share with you.
Hope this helps.
