💡 Electric Potential Equivalence:
$$1\text{ Volt} = 1\text{ Joule / Coulomb} \implies 1\text{ statV} \approx 299.79\text{ V}$$
Understanding Electric Potential Difference
Electric potential ($V$) measures the work required per unit charge to move a test charge between two points:
- Definition: $$V = \frac{W}{Q} = \frac{\text{Joules}}{\text{Coulombs}}$$
- Ohm's Law: $$V = I \cdot R$$
- Electric Field Relation: $$E = -\nabla V \implies \Delta V = -\int \vec{E} \cdot d\vec{s}$$
- Statvolt ($cgs$): Exactly $1\text{ statV} = 1\text{ erg / statC} = 299.792458\text{ V}$.
