6 FAQs about [Capacitor distance electric field strength]
How does the field strength of a capacitor affect rated voltage?
The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates. This factor limits the maximum rated voltage of a capacitor, since the electric field strength must not exceed the breakdown field strength of the dielectric used in the 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: where the symbol ∝ means “proportional to.”
How do you find the capacitance of a parallel-plate capacitor?
The electric field between the plates of a parallel-plate capacitor To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.
What is a capacitance of a capacitor?
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
