Consider the circuit shown where C_(1) = 6 mu F, C_(2) = 3 mu F and V=20 V. Capacitor C_(1) is first charged by closing the switch S_(1). Switch S_(1) is then opened, and the charged capacitor is connected to the uncharged capacitor C_(2) by closing S_(2).

Answer»

Total charge that has FLOWN through the battery is `120 MU C.`
Final charge on `C_(1)` after opening switch `S_(1)` and closing switch `S_(2)"is" 80 mu C.`
Final charge on `C_(2)` after opening switch `S_(1)` and closing switch `S_(2)"is" 40 mu C`
Total heat PRODUCED after closing switch `S_(2)"is" 1.8 MJ.`

Answer :`(A,-B,C)`
