Your brain uses as much power as a ten watt battery.
-Helen Brosnan
This steam cleaner does not use any electrical power.
Moving electrical power from generating point to use point.
We really have no accepted definition of or way to measure "brain power" so it is hard to say what the maximum possible power is or how much of that people use. No credible neuroscientist holds with the 10% dogma. By almost any reasonable measure we use more than that.
the main diffrent between electrical and electronics is Electrical is study of electriccity and electronics is study of the electical or databus controlle circuit. All machine need electrical Power. how much power it need? which electrical contolled it need? that study in Electrical but in Electronics how much power we need? and how to create that power for that we use some electronics circuit. that sutdy i electonics. It is a simple diffrent between electrical and elecronics. ANSWER: The difference is the study of electrons behavior. Electrical main concern is electrons flow. Electronics is a study of electrons emission.
The power rating of an electrical appliance represents the rate at which the appliance uses electrical energy. It is typically measured in watts and indicates how much electricity the appliance consumes when it is in use. Higher power ratings suggest that the appliance uses more energy.
About 10% of your brain ---------------------------------- Actually you use just about all of your brain
You use your brain for 100% of your life. When your brain stops functioning, so do you.
The load that is connected to the circuit is what draws the power of the electrical circuit.
don're rely too much on technology such as your cellphone to do simple calculations. try to use brain, not so much electronics
The Garmin GPS uses very little electrical power. However, it is best to unplug it from your car after use. If you leave it left plugged in for a span of 70+ days it could begin to drain your car battery.

If the efficiency is 0.5, then the useful lifting power is 0.5 of the powerthat it must consume in order to do the job.2,500 W = 0.5 of input power.input power = 2,500 / 0.5 = 5 KW.
