Q44. Which of the following statement is NOT true, when two capacitors charged to different potentia

Q: What is the correct answer for CUET UG Physics Q44?

The correct answer is d. When two capacitors charged to different potentials are connected in parallel, charge flows from the higher potential capacitor to the lower potential capacitor until a common potential is established across both. (a) During this charge redistribution, current flows through the connecting wires, and some energy is dissipated as heat, meaning some energy is always lost. So, this statement is true.

When two capacitors charged to different potentials are connected in parallel, charge flows from the higher potential capacitor to the lower potential capacitor until a common potential is established across both. (a) During this charge redistribution, current flows through the connecting wires, and some energy is dissipated as heat, meaning some energy is always lost. So, this statement is true. (b) The total charge in the isolated system of the two capacitors is conserved. Therefore, the amount of charge lost by the capacitor that discharges (with higher initial potential) is precisely equal to the amount of charge gained by the capacitor that charges further (with lower initial potential). So, this statement is true. (c) Charge continues to redistribute until the potential difference across both capacitors becomes equal, reaching a common potential. So, this statement is true. (d) The potential lost by one capacitor is (V_initial_1 - V_common) and the potential gained by the other is (V_common - V_initial_2). These potential changes are generally not equal unless the capacitors have equal capacitances and initial potentials that are symmetrically distributed around the final common potential. Therefore, this statement is NOT true. The question asks for the statement that is NOT true.
