Question
A parallel-plate capacitor has plates of unequal area. The larger plate is connected to the positive terminal of the battery and the smaller plate to its negative terminal. Let Q, and Q be the charges appearing on the positive and negative plates respectively.
Options
Q, > Q
Q, = Q
Q, < Q
The information is not sufficient is decide the relation between Q, and Q.
Solution
`Q_+ = Q_-`
The charge induced on the plates of a capacitor is independent of the area of the plates.
`therefore Q_+ = Q_-`
