Hi
My octogenarian mother has become fearful that the small black transformers which are supplying electricity to various things around her flat might burst into flames.
She has a good reason for her fears, one of them some time ago became very hot indeed to touch. She has had it fixed by an electrician she knows and it is now always at a mildly warm temperature.
However after that experience she now has taken to unplugging these transformers all the time which actually involves plugging and unplugging quite a lot just to turn things on or off.
Conversely in my little house I just leave these transformers plugged in and "on" all the time. I do turn off the things they are supplying but I don't bother turning off at the wall very much.
Is my mother right or am I right?
Perhaps the truth lies somewhere in the middle?
