POTENTIAL GRADIENT

DEFINITION: potential gradient is the space rate of change of potential with distance.

If the dielectric is homogeneous and the electric field is steady and uniform, the potential gradient is a constant.

Potential Gradient is denoted by g.

It is defined as :-
           
g=dVdx

When the potential gradient is a constant,  then 
     
g=Vt volt per unit thickness

where, V = the potential difference between the dielectric of thickness t

Potential gradient is expressed in volts per meter.
