3 capacitors with capacitance 5µ F, 6µ F and 7µ F are arrange in series combination with a battery of 5V, then which capacitor has more potential difference across a plates:
Correct answer: A. 5µ F capacitor
- A. 5µ F capacitor
- B. 6µ F capacitor
- C. 7µ F capacitor
- D. Same potential difference across all
Explanation
Option A is correct as: Q=CV Q/C=V Capacitance is inversely proportional to Voltage So 5µ F capacitor will have maximum potential difference across its plates.

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.
