Question

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.

Answer 1

`(i) Q=(30+20+1)mu C=60 mu C`
(ii) `U_("total")=(1)/(2)xx6xx10xx10=300mu J`
`(iii) "heat produced"=60xx10-300=300mu J`
(iv)`U_(3mu F)=(1)/(2)xx3xx10xx10=150 mu J`
