There are two round holes on the plug, and their magical use is little known.
The two round holes on electrical plugs are not just for design; they serve important purposes.
First, they help secure the plug in the socket, as some outlets have bumps inside that fit into these holes, preventing the plug from easily slipping out.
Second, they allow for better electrical contact by ensuring a tighter connection between the prongs and the socket, reducing the chances of sparks or loose connections. This simple yet effective feature enhances safety and efficiency in everyday electrical use.
