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.
Therefore the magnitude of the electric field inside the capacitor is: The capacitance C of a capacitor is defined as the ratio between the absolute value of the plates charge and the electric potential difference between them: The SI unit of capacitance is the farad (F).
The electric field strength is, thus, directly proportional to Q. Figure 19.5.2: Electric field lines in this parallel plate capacitor, as always, start on positive charges and end on negative charges. 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.
This ability is used in capacitors to store electrical energy by sustaining an electric field. When voltage is applied to a capacitor, a certain amount of positive electric charge (+q) accumulates on one plate of the capacitor, while an equal amount of negative electric charge (-q) accumulates on the other plate of the capacitor. It is defined as:
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.
In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.
