If a light bulb is dead, does it still consume electricity if the switch is in ON?
It's been a week since a light bulb in the bathroom died. I'm wondering if the bulb is dead, does it still consume electricity if the switch is in ON?
The light is completely dead, no light whatsoever.

Can I safely use a 9w LED bulb in place of a 40w incandescent?
I bought a reading lamp that on the box says: Max 1x40W
The shop also sold me an LED light bulb that says: 9W=75W
So my question is, can I use light bulb or not? I am confused between the 75W and the max of 40W mentioned for the lamp
