    So recently a night light burned out in my grandparent's outlet. They just bought it, so I read the voltage across all points. Ground to neutral was about 0.68 volts, so that was fine. Hot to ground was 120 volts, so that was fine. Hot to neutral though, it reads 120 volts, but if I move the probe up in the outlet slot a tiny bit, the reading changes to 10 - 15 volts. Is that normal? Maybe the outlet is dirty near the top and is causing a lot of resistance? I have no idea what could cause it.

    You're not making connection with the neutral bar. Touching the hot side by itself will give you these types of readings.

    What? Both probes are connected. Do you mean that inside the slot, there is an empty space on the top with no metal?

    I get it now. If there's an empty spot, it's just the magnetic field inducting a current or something. Sorry. I'm new to electronics.

    It's OK. This is a teaching site. We've seen worse mistakes.;)
