I replaced a ceiling light in a 1950's-wired apartment. There are insulated black and neutral wires, but no ground connection (fixture has ground wire but just connected it to mounting bar). If wired backwards, what happens when I flip the switch? When I touch the fixture while power and/or switch are on? [more inside]
When I'm sitting in the room with the breaker box to my house, I hear a series of short buzzes, like "bzzzt." The noise seems to be coming from the breaker box, and I notice that a faceplate to one of the switches is missing (breakers were last switched off a month or two ago, when new heat pump was installed.). Here is (or should be) the image (if not, there's just copper surface where the breaker faceplate should be):

One of our circuit breakers tripped, and it won't return to its "on" position. I push it toward "on," but it doesn't stay, just returns to a middle position between on and off. It serves only a single hallway in the home, and nothing is plugged in there. Does the breaker need to be replaced? Should I call an electrician?
I heard this weird buzzing sound coming from my basement today, and I eventually opened up the ceiling and traced it to this transformer or something that's up in there. I tapped it with a piece of non-conductive material and it stopped buzzing. Tapped it again, it started buzzing more quietly, and then I tapped it again and it was silent. Anyone have any idea what this is, and why it's there? The house is from 1952 and doesn't have any electrical issues that I know of. Pictures: Pic 1 Pic 2 Pic 3

This switch/receptacle has been miswired for years. For starters, neither device had the grounding wires attached. I want to put things the way they should be. [more inside]

When my living room lights are off, touching the screws on the faceplate for the electrical switch gives me a tiny little frisson of electricity. When my living room lights are on, I get a fairly painful shock from touching the screws on the faceplate. How dangerous is this? [more inside]

I know, I know, light bulbs seem to fail in clusters, but I don't think this is to do with putting a bunch of lights in at the same time. This week for instance, I got up and turned on my kitchen lights (8 x 50w small spots) and one blew and tripped my Ground Floor Light fuse. A day later and I get home and turn on the same lights, another goes and trips the lights circuit again. Later in the week, another goes in my study. I replaced all the bulbs today. I turn them on, everything is fine, I go outside and turn on the porch/side lights (3 x 60w) and two of them blow. I nearly always have an inop light or two. My question is this : Is there an electrical fault which might explain this pattern of failure ? Thanks

We just moved into a townhouse. In the guest bathroom, the light and fan are operated by the same switch, so that the fan automatically comes on when you turn on the light. We hate the sound of the fan and would prefer to have two separate switches, one for the light and one for the fan. How complicated is this to do? Is it something we could reasonably learn how to do ourselves or should we leave it to an electrician?
