Vector Field and Electric Field Lines The electric field is a vector field: v E ( v r ) = v E ( x, y, z ) = E x ( x, y, z ) ˆ i + E y ( x, y, z ) ˆ j + E z ( x, y, z ) ˆ k Electric field lines: graphical representation of vector field. Properties of electric field lines (electrostatics): Electric field lines begin at positive charges or at infinity. Electric field lines end at
