Why does tester show power to light when the wall switch is off?

If you are using a proximity tester that senses current flow in its vicinity, it is possible that the box where the light is connected may also be used as a junction box for a separate device.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
