Why is there still some voltage?

I am running a second light receptacle from an existing light receptacle. Existing wiring is armored cable. When I throw the wall switch to "off", I still read 10volts at the existing receptacle but zero amps. How come? Shouldn't I be reading zero volts?

What are you usimng to measure the voltage. If you have an analog meter, you should see zero. If you have a digital meter and see a small voltage, it is a phantom voltage - common problem with digital meters.

For safety you should be turning off the power at breaker or fuse box. Stray voltage - Wikipedia, the free encyclopedia
