Interview Question which is simple

[Ogu Reginald]

Please what is the idea, principle and mode of operation in which a wrist watch whose battery is down and which has stopped working starts to work immediately you put it on your hands?
Does it mean that it is using someones blood or something else?

 

[1/2dime]

Where is the battery at that point? E

 

[chuckey]

its because the warmth of the persons wrist has raised the batteries voltage enough for the watch to start working.
