📖 Physical Concept & Comprehensive Explanation
Electric potential dictates the direction of spontaneous charge flow, moving positive charge from higher to lower potentials. A voltage difference between conductors drives electrical current across circuits.
🎯 High-Yield Revision Points
- ✓Electric Potential = Work / Charge (V = W/q).
- ✓1 Volt = 1 Joule per Coulomb.
- ✓Potential difference drives electric current.
