Study Tips & Quick Start
Quick summary:
- Electrostatic fields are conservative → V is path-independent
- Use symmetry + superposition to build V and C
- For capacitors: decide constant V (battery) vs constant Q (isolated)
Practice:
- Derive V for a point, dipole, ring, and sphere
- Compute C for parallel-plate, spherical, cylindrical
- Explain energy changes with/without a battery when inserting a dielectric
