31: Capacitors
- #7A 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.
(a) Q, > Q
(b) Q, = Q
(c) Q, < Q
(d) The information is not sufficient is decide the relation between Q, and Q.digAnsr: bAns : (b) `` {Q}_{+}={Q}_{-}``
The charge induced on the plates of a capacitor is independent of the area of the plates.
∴ `` {Q}_{+}={Q}_{-}``
