Do Different Sized Capacitor Plates Hold the Same Charge?

[lala-e-sehrai]

if the capacitor plates are of different sizes and it is connected to battery, will even then the two plates get charges of exactly the same magnitude?

 

[Meir Achuz]

Yes. If the capacitor starts out with zero total chare, it must remain with zero total charge.

No, the two plates will not necessarily get charges of exactly the same magnitude if they are of different sizes and connected to a battery. This is because the amount of charge that a capacitor can hold is directly proportional to its capacitance, which is determined by factors such as the size and distance between the plates. Therefore, if the plates are of different sizes, they will have different capacitances and thus different amounts of charge on each plate. However, the overall charge on the capacitor will still be the same, as it is determined by the voltage of the battery.
