When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates. This result can be obtained easily for each plate. Therefore when we put

Relation between Electric Field and potential
The relationship between electric field (E) and potential (V) is given by the equation E = - dV/dx, where dV represents the change in potential and dx represents the change in distance. In simpler terms, the electric field is the negative gradient of the potential. This means that the electric field points in the direction of decreasing potential.

6 FAQs about [Relationship between capacitor field strength and electric potential]
What is the relationship between electric field & potential & capacitance?
The potential difference across a capacitor is determined by the charge stored and the capacitance, and their relationship is given by the equation V = Q/C. Relation between Electric Field & potential - Electrostatic Potential & Capacitance for Class 12 2024 is part of Class 12 preparation.
What is the relationship between electric field and potential?
The relationship between electric field (E) and potential (V) is given by the equation E = - dV/dx, where dV represents the change in potential and dx represents the change in distance. In simpler terms, the electric field is the negative gradient of the potential. This means that the electric field points in the direction of decreasing potential.
Is field strength proportional to charge on a capacitor?
Since the electric field strength is proportional to the density of field lines, it is also proportional to the amount of charge on the capacitor. The field is proportional to the charge: E ∝ Q, (19.5.1) (19.5.1) E ∝ Q, where the symbol ∝ ∝ means “proportional to.”
Why does a dielectric reduce the field strength of a capacitor?
Since the field lines end on charges in the dielectric, there are fewer of them going from one side of the capacitor to the other. So the electric field strength is less than if there were a vacuum between the plates, even though the same charge is on the plates. The voltage between the plates is , so it too is reduced by the dielectric.
How does a capacitor store potential energy?
Work is required to store positive and negative charges on the plates of a capacitor, thereby storing Potential Energy in the E-field between the capacitor plates. A graph of the charge building up on the plates, Q, versus time is shown at right. Below that is a graph of ∆V versus Q as the capacitor becomes fully charged.
