Find the charge appearing on each of the three capacitors shown in Fig.

Text Solution

Verified by Experts

Capacitors B and C are in parallel.
Therefore, their total capcity `= 4+4 = 8 mu F`
The total capacity of `8 mu F` and capacitor A which are in series w.r.t battery is given by
`:. (1)/(C_(s)) = (1)/(8) + (1)/(8) = (1)/(4), C_(s) = 4 mu F`
Total charge `= C_(s) V = 4xx12 = 48 muC`
This is the charge on A. and also on the combinatin of B and C. As capacities of B and C are equal the total charge is shared equally between them.
`:.` Charge on B = Charge on C `= (48)/(2) = 24 muC`
