Three initially uncharged capacitors are connected to a battery of 10V is parallel combination find out following
(i) charge flow from the battery
(ii) total energy stored in the capacitors
(iii) heat produced in the circuit
(iv) potential energy in the `3mu F` capacitor.

Explanation

(i) ` Q= ( 30+20+10) mu C = 60 mu C `
(ii) ` U_("tota") =(1)/(2) xx 6xx 10 xx 10 = 300mu J `
(iii) Heat produced `= 60xx 10 - 300=300 mu J `
(iv) ` U_(3 mu F) = (1)/(2) xx 3xx 10 xx 10 = 150 mu F `
