If the amount of work W is required to move a charge Q from one point to another then the potential difference between the two points is given by
Correct answer: A. V=W/Q
- A. V=W/Q
- B. V=Q/W
- C. Q=W/V
- D. Q=V/W
Explanation
The potential difference (V) between two points is defined as the work (W) required to move a unit charge (Q) from one point to the other. Mathematically, this is expressed as:V = W/QThis equation shows that the potential difference is directly proportional to the work done and inversely proportional to the charge

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.
