D.2.14 (HL)—Electric potential Topic Practice
Practise finding and sketching electric potential for charges and conducting spheres, using scalar addition, conductor rules and clear V-r graphs.
How this is tested
- add scalar potentials with V = kQ/r to find the total V at a marked point or symmetric centre
- use conductor rules to state V and E inside a hollow sphere: constant potential, zero field
- sketch a V-r graph for spheres or two charges, showing flat conductor sections and curved outside parts
