There are two lights at the entrance to the kitchen. I rarely use them. Recently, I found that one light was off. After two weeks, I have finally decided to fix it. I removed the old bulb, which was labeled 220 V, 50 W. I checked the resistance and found it infinite. Burnt out, I thought. I took out a new bulb and checked it. The resistance was 0. OK. I installed the bulb and turned on the switch. No luck. The light was still off. I checked the voltage at the bulb socket and found it only 50 V. I removed the lamp from the wall and checked the voltage of the two incoming wires again. Still, 50 V. Since the light was working before, it's only reasonable to assume that the voltage was 220 V.
So, the question is why the voltage is 50 V now? What could cause it to be 50 V? There is a hole, chewed by a mouse, near the other light. I don't think that would matter, would it? This house has 3-phrase, 220 V power supply.
