Ampere.second is the unit of:
Correct answer: B. Charge
- A. Power
- B. Charge
- C. Potential Difference
- D. Current
Explanation
The correct answer is Charge because the unit ampere.second represents a coulomb, which is the standard unit of electric charge. According to the definition of a coulomb, it is the amount of electric charge transported by a constant current of one ampere in one second. In contrast, the options for Power (watts), Potential Difference (volts), and Current (amperes) are all different physical quantities with their own distinct units. Power relates to energy transfer, potential difference measures energy per charge, and current measures the flow of electric charge per unit time, but none of these relate directly to the unit of charge itself.

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.
