Electrostatic Potential and Capacitance — Class 12 ISC Physics revision notes
A 5-page visual revision sheet for Electrostatic Potential and Capacitance, written for Class 12 ISC Physics. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Electrostatic Potential and Capacitance sheet covers

- Equipotential surfaces
- Potential due to standard bodies
- Potential energy of a system
- Conductors, restated in terms of potential
- Capacitance
- Combinations, and the energy stored
- in series
- in parallel
- energy stored
- with a dielectric slab
- with a conducting slab
- spherical capacitor
- Capacitance of a parallel plate capacitor
- The two questions to ask before any dielectric problem
- Where the energy of a capacitor actually is
- Van de Graaff generator
- dielectrics and polarisation
- polarisation
- The dielectric, quantitatively
- Self energy of a shell and of a solid sphere
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Physics chapter by chapter against your real exam dates and free hours, and when the plan reaches Electrostatic Potential and Capacitance the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
