The intensity of the electric field or the electric field strength can be thought of as the gradient of the field. It is easy for us to visualise the gravitational field, as we are more affected by it. It acts upon our mass - we rarely have a net charge! With gravity, the steeper the gradient of a slope the greater the force acting on an.

A capacitor is a device used to store electrical energy. The plates of a capacitor is charged and there is an electric field between them. The capacitor will be discharged if the plates are connected together through a resistor. The charge of a capacitor can be expressed as Q = I t (1) where
Since electric field strength has direction, it is a vector quantity. Intensity refers to the magnitude or amount. Therefore, electric field intensity means the magnitude of the field’s strength. In summary, electric field intensity or strength is written as: We have discussed electric field intensity at a point due to a single charge.
U is the electric potential energy (in J) stored in the capacitor’s electric field. This energy stored in the capacitor’s electric field becomes essential for powering various applications, from smartphones to electric cars (EVs). Dielectrics are materials with very high electrical resistivity, making them excellent insulators.
