Re: Answer this riddle
Those readings are pretty weird. Hopefully you're not reading resistance since that won't mean anything on a power circuit.
Analog meters have a certain amount of non-linearity in the scale. I assume you have an analog meter based on the settings you're quoting (250v and 50v). If you set the meter up such that the needle is in the lower half of the scale, the readings can be off by a few volts. Also, take note if your meter has a V/2 setting. The V/2 switch is often provided to help get your meter to read higher on the scale for better accurace. For example, if you're on the 50V setting and the V/2 switch is active, you'll actually be reading 25V full scale - not 50v. Also, double check the holes your probes are inserted in. Typically the black will be in a "COM" or "-" jack, while the red will be in a V-Ohms terminal.
If you are using an analog meter, take the batteries out of it. Throw it in the back of your tool drawer and buy a cheap digital meter. A decent meter can be had for less than $20. I bought a pretty nice meter for my father in-law last christmas at Sears for $38.
