Induced charge distribution on conductor via “method of images”
- Consider a source charge brought close to a planar conductor:
- Charge distribution “induced” on conductor by source charge
- conductor is equipotential
- E-field is normal to surface
- this is just like a dipole
- Method of Images for a charge (distribution) near a flat conducting plane:
- reflect the point charge through the surface and put a charge of opposite sign there
- do this for all source charges
- E-field at plane of symmetry - the conductor surface determines s
