Questions
A capacitor of capacitance C is charged by connecting it to a battery. The battery is now removed and this capacitor is connected to a second uncharged capacitor of capacitance C'. If the charge distributes equally on the two capacitors, the ratio of the total energy stored in the capacitors after connection to the total energy stored in them before connection is:
detailed solution
Correct option is B
Ei=Q22C ....(1) After connection, Ef=Q2′22C+Q222C′ ∵ C=C′ ⇒ EfEi=12Talk to our academic expert!
