| 95% | Series + Parallel equivalent capacitance derivation — Step-by-step derivation; always state the SAME-CHARGE (series) and SAME-VOLTAGE (parallel) constraints upfront. | 5 MARKS |
| 80% | Parallel-plate capacitor with dielectric — Derive C = Kε₀A/d. Explain polarisation reduces field → lower V → higher C. | 5 MARKS |
| 75% | Energy stored + redistribution — U = ½CV². Sharing: Q conserved, energy NOT conserved (heat + radiation loss). | 4 MARKS |
| 80% | Numerical: V due to multiple charges — V_total = Σ kq_i/r_i. Algebraic sum (sign of V matches sign of charge). | 3 MARKS |
| 60% | Equipotential surfaces — properties + types — Perpendicular to E. Work on surface = 0. Closer = stronger field. Never intersect. | 3 MARKS |
