Some electric and electronic appliances and devices emit ElectroMagnetic Radiation (EMF/EMR) and consume electricity even when on standby mode, even when not in use. The best way to reduce this emission and electricity consumption to 0 is to unplug the devices from the electricity power outlet. However this is not always easy to do and can sometime be a little bit dangerous. In this clip we will see how a multi socket power outlet with a power switch can solve this issue. We will see that all the devices emit EMR when connected to the power source and does not emit any EMR when the power switch is turned off.
