SUMMARY
Potential difference, denoted as ΔV, quantifies the difference in electrical potential energy per unit charge between two points, such as point A (100 V) and point B (0 V). The calculation of ΔV is straightforward: ΔV = V_A - V_B, resulting in ΔV = 100 V in this scenario. This value indicates the work required to move a charge from point A to point B, specifically 1 joule of energy per coulomb of charge moved, establishing a voltage difference of 1 V for a 1 coulomb charge.
