Question:medium
Two identical capacitors, have the same capacitance \( C \). One of them is charged to potential \( V_1 \) and the other to \( V_2 \). The negative ends of the capacitors are connected together. When the positive ends are also connected, the decrease in energy of the combined system is â
Two identical capacitors, have the same capacitance \( C \). One of them is charged to potential \( V_1 \) and the other to \( V_2 \). The negative ends of the capacitors are connected together. When the positive ends are also connected, the decrease in energy of the combined system is â
Show Hint
The energy lost when two capacitors are connected together depends on the difference in their voltages before the connection.

- \( \frac{1}{4} C (V_1 - V_2)^2 \)
- \( \frac{1}{2} C (V_1 + V_2)^2 \)
- \( \frac{1}{4} C (V_1 + V_2)^2 \)
- \( \frac{1}{4} C (V_1 - V_2)^2 \)
Show Solution
The Correct Option is A
