Term

Electrical potential, V, like the electric field, is created what and tools

Definition

source charges. - potential of a point charge, Vpoint= 1/4pieeo x q/r - principle of superposition

Term

For multiple point charges

Definition

Use superposition V= V1+V2+V3+...

Term

For a continuous distribution of charge steps

Definition

1)Model as a simple charge distribution 2) Draw picture - Coor system -Identify point of potential in interest 3) Solve by setting up sum equation V= sum n and i=1 = Vi - Divide charge into point- like delta Q - Find potential due to delta Q -Use charge density to replace delta Q with an integration coor, then sum n= Q/A A=> rod=>pieR^2 A=>disk=> L x w= 2pier^2 x deltar V is easier than Efield as its a scalar
