An electrical device can still be on and charging if the fan is off. If the device is plugged in to the wall, or connected to a battery, chances are it is charging.
Anything device can transform electrical energy into other form of energy. This is called an electrical load.
how does input device work
If it is a physical switch, this is called a "relay" or a "contactor". If it is a semiconductor device, it is typically a triac, SCR or a thyristor.
yes
An electrical fan converts Electrical Energy to ME.
A fan
An electrical device can still be on and charging if the fan is off. If the device is plugged in to the wall, or connected to a battery, chances are it is charging.
Yes you could cool down any electrical device by having increased airflow around the device and a fan is one method to achieve it
battery
The rate at which an electrical device converts energy from one form to another is called electrical power. The rate at which electrical energy is changed to another energy form electrical power.
If it pertains to electrical controls on a machine then the safety device is called an emergency stop button.
Nonconductor
Yes, because it is not 100 % efficient at converting electrical energy into kinetic energy.
It is called a speaker.
We licensed electricians call the device an OHM meter.
