My question is simple, if the light plug switch is on, and nothing is plugged in, does this consumes any electricity? or even if a laptop/mobile charger is plugged in but not connected to laptop or mobile on the other side, does it consumes electricity?
Hahaha, no i always turn off the switches and plug out the charger , was just asking for knowledge anyway why does chargers consume electricity? due to the tiny transformers inside them?
unplugging adapters/chargers helps in places like Pakistan voltage fluctuates enormously, in villages especially.
I don't know much technically, but I think in terms of law of conservation of energy. If something is generating heat, sound or light or any type of mechanical motion then it means electricity is being consumed.
no it doesn't consume electricity and keeping adapters plugged in is good habit i didn't unplug them at
In side a charger step down Transformer is there. To know the details of Transformer you can click here. It does not matter you draw anything from the secondary end or not. the primary will provide electricity to the primary coil and that will induced magnetic filed from that magnetic field electric will be generated in secondary coil and due to all these process electricity will be consumed as long as it plugged to the electric socket .
^ Plugged in but switch is off, does this consumes electricity?
the only real answer is: it depends. cheap wall sockets leak electricity, i have seen that happen too many times. it might be very low current but it's leakage when it is off.Plugged in but switch is off, does this consumes electricity?
