Question Plugged In TV & Light

I have a spare bedroom with a TV & lamp I ususlly leave plugged into the wall outlet. Even though neither is turned "on", are they using any electricity?

The lamp, no. The TV probably is, unless it is really old. TV's have prewarm circuits for the tube filaments, and also use some power for memory circuits for the channels, etc.

If the TV uses a remote then it does for sure. You need power run the remote circuits in the TV.

Speaking of old TVs and standby power, I've got an old RCA with a remote that uses ultrasound. You'd think that would sure suck the power compared to a modern IR setup. Measured less than 1W when off, though. Go figure.

Being it has a remote, it would still draw power to power the remote receiver circuitry. They often use simple logic, rather than a microcomputer.
