Two capacitors of capacities $C_1$ and $C_2$ are charged upto the potential $V_1$ and $V_2$, then condition for not flowing the charge between on connected them in parallel is

  • A
    $C_1=C_2$
  • Correct answer
    B
    $C_1 V_1=C_2 V_2$
  • C
    $V_1=V_2$
  • D
    $\frac{C_1}{V_1}=\frac{C_2}{V_2}$

Solution

If charge on both the capacitors is same, then transfer of energy does not take place. $Q=C V$ $\therefore \quad C_1 V_1=C_2 V_2$ It is the required condition.

Hence, the correct answer is option: 'B'.
