While roaming around the college building, I found the arrangement of the power sockets in such a way that it is difficult to fit the two power plugs simultaneously.
Almost all the power sockets are arranged in a vertical fashion that means one socket over another. The problem for such kind of arrangement is that when a power plug is fit on the upper socket, the cord of this plug makes it difficult for the second plug to fit into the lower socket. The problem is shown in the picture 1.
There might be some different(probably stronger) reason behind such arrangement, but i simply find it difficult to plug in two power plugs simultaneously. And obviously the problem is due to the vertical attachment of the sockets to the wall. A simple solution may be the arrangement of the socket horizontally. By doing so, both the power plugs fits into the sockets side by side at the same time.
