Let Q denote charge, V denote potential difference, and U denote stored energy. Of these quantities, capacitors in parallel must have the same:
Correct answer: B. V only
- A. Q only
- B. V only
- C. U only
- D. Q and U only
Explanation
When circuit elements are connected in parallel, they are connected across the same two points in the circuit. By definition, this means the potential difference (V) across each parallel element must be the same.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
