Is there any device in the world which have 100% Efficiency??

I say 220/12*100=1833%. Now what to say?Nab AC Analysis said:I think that stepup transform produce 100% efficiency its not a silly question though.... if you provide an input of 12 volts and try to get 220 volts stepup output... then according to Efficiency=Vout/ Vin x 100= 220/12= 100%
Now what to say??

sure.. we can contruct a kettle to have high efficiency , but not 100% -> which comes when the power o/p (used) == Input Power.Dr.EM said:Just while were here, I have always wondered about electric kettles. Are they efficient? I mean, energy is usually wasted as heat, but the device is trying to produce heat so surely there is little "waste". The same applies to electric fires etc I guess, probably moreso. I can see that energy is lost in transfer to the water, but the heater itself (do heating elements light up inside like toaster wires?).
Nab AC Analysis said:I would like to thanks all of you to participate on this silly discussion.... but its not silly in a way.... Nothing is perfect i believe that transformers cannot be the perfect device , they are not efficient as 80% ... as they have core lossses, winding and tap losses.... But the figures disagree with me....
