4. Key Points Potential is Inversely Proportional to distance Electric Field Strength is Proportional to the Inverse Square of the distance Equipotentials are always perpendicular to Electric Field Lines

7. Key Points Potential is Inversely Proportional to distance Electric Field Strength is Proportional to the Inverse Square of the distance Equipotentials are always perpendicular to Electric Field Lines You can move along an equipotential without doing any work because the distance you move in the direction of the force is always zero Where Equipotentials are close, field strength is high

8. Equipotential

9. Key Points Between two differently charged parallel plates equipotentials are always – Parallel to the plates – Equally Spaced This means that that electric field is always – Pointing directly from +ve to –ve – Uniform in all places between the plates E = V/d V d
