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

Options

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

Correct answer

B. $C_1 V_1=C_2 V_2$

Step-by-step 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.
