A battery is used to charge a a series combination of two identical capacitors...?

If the potential differences across the battery terminals is V and the total charge Q flows through the battery during the charging process then the charge on the positive plate of each capacitor and the potential difference across each capacitor are:

A) Q/2 and V/2, respectively

B) Q and V, respectively

C) Q/2 and V, respectively

D) Q and V/2, respectively

E) Q and 2V, respectively

explain please

    D) Q and V/2, respectively

    Capacitors in series all have a common charge.

    Master voltage is divided up among capacitors.

    Similar rules exist for resistors of which you may be more familiar, when you replace the word "charge" with "current" and "capacitor" with "resistor".

    In series, if one battery is in additional desirable effective structure than the different, it is going to fee swifter and its voltage will upward push swifter, so the poorer battery has a smaller voltage to fee it, and it may no longer completely fee earlier you prefer to charm to ability from it by the inverter. The battery with the decrease voltage ought to desire replacing. It makes more desirable experience to change both batteries so as that the hot ones are as on the point of being same as achieveable, this manner you get the longest achieveable existence from the pair. Are you particular the inverter needs 23 volts ? i ought to take the decrease voltage battery and fee it completely from yet another source like a automobile charger, then placed it again and observe the way it behaves. i imagine also that both batteries might want to be examined on load to be certain in the adventure that they are nevertheless usable.
