What are some items around the house that use electromagnetic spectrum?

Answer 1

The one that you unplug and do not use. No one can safely say that any one appliance, or type of appliance uses the least electricity as there is no single standard for power consumption of these appliances; beyond general requirements.

I recently bought a 3 watt nightlite for 3 bucks. Gotta be the least user of all appliances.

Answer 2

The most powerful producer of EM waves is probably your microwave oven. Other items include Wi-Fi & bluetooth devices, mobile phones, remote central locking car keys, R/C toys, wireless baby monitors, wireless headphones, smart electricity meters & two way radios.

Answer 3

Anything that plugs into the wall is using AC electricity.

Anything running on batteries is using DC power.

Many appliances have a power converter/adapter which converts AC to DC power before being run into the appliance. So although they plug into an AC source, the device actually uses DC.
