呢條既(c)(d)(e)(f)都唔知點做 有冇高手可以幫解答一下 question like: http://i813.photobucket.com/albums/zz57/suetyingbb/222.jpg

最佳解答:

Ans from (a): 0.0235 C c) Suppose that the common voltage is V, then by the conservation of charge: (47 x 10-6 + 5 x 10-6)V = 47 x 10-6 x 500 V = 500 x 47/52 = 451.9 V d) Using CV = Q, Q1 = 47 x 10-6 x 451.9 = 0.0212 C e) Ans from (a) - ans from (d) since charge is conserved, hance ans is: 0.0235 - 0.0212 = 0.0023 C f) 0.5 x (47 x 10-6 + 5 x 10-6) x 451.92 = 5.31 J 2010-04-16 00:28:37 補充： (c) 中的 52 是由47 + 5 得出.
