When a battery is connected to a capaciog+z gb5 upkh7i(+ gn5tor, why do y9s( 0ca q t pu -bydzy)h1*zrx+*xvk-the two plates acquire charges of the same magnitude? Will this be true if the twy-*ycxd9t1vbaq-u*yx+(pkhzrs)0 z o conductors are different sizes or shapes?
参考答案:
Any imbalance of charge
that might exist would quickly be resolved.
Suppose the positive plate, connected to the positive terminal of the
battery, had more charge than the negative plate. Then negative charges from the negative
battery terminal would be attracted to the negative plate by the more charged
positive plate. This would only continue
until the negative plate was as charged as the positive plate. If the negative plate became “over charged”,
then the opposite transfer of charge would take place, again until equilibrium
was reached. Another way to explain the
balance of charge is that neither the battery nor the capacitor can create or
destroy charge. Since they were neutral
before they were connected, they must be neutral after they are connected. The charge removed from one plate appears as
excess on the other plate. This is true regardless of the conductor size or
shape.
