When dealing with practical devices, we ofaulm ayslinlo4;5 ;8 *ten (rw*;gr rr w;itake the ground (the Earth) to be 0 V. If, instear r(; rww*i;grd, we said the ground was how would this affect (a) the potential V, and (b) the electric field E, at other points?
参考答案: (a) V would decrease by 10 V at every location.
(b) E is related to the change in electric
potential. Decreasing the potential by
10 V everywhere
would not affect the changes in potential from one location to
another, and so would not affect E.
