Talk:Potential gradient

From Wikipedia, the free encyclopedia

More accurate: "The potential gradient has the same value as the component of the electric field in the direction of the potential gradient. If we choose the directions so that they are the same, the values magnitude of the electric field will be the same as that of the potential gradient. Notice that volt per meter will reduce to newton per coulomb." - [1]

\mathbf{E} = - \nabla V / \nabla s - [2]

\mathbf{E} = -grad \phi - [3] (also has some about corona discharge) also [4]

\mathbf{E} = -V / d - [5]

\mathbf{E} = -dV / dr_{max} - [6]
