Field Visualization

The electric field at a point is the vector sum of fields from all charges. Potential is a scalar and adds algebraically.

Electric Field: E = kQ/r^2

Electric Potential: V = kQ/r

Coulomb's Constant: k = 8.99e+9 N*m^2/C^2

Field Direction: Away from +Q, Toward -Q

Superposition: E_total = sum of E_i
