Why does C become larger after inserting the glass plate in the capacitor? |Focus on mid-to-high-end brand capacitor manufacturers

by:Shenmao     2021-06-26
Because the capacitor is put into the glass to change the dielectric constant of the dielectric. Polarized charge will be generated on the contact surface of the glass and the plate. Generally speaking, the equivalent charge is less and the electric field strength is small, so it can be stored under the same voltage The capacity of the capacitor is too much. Different dielectrics have different relative permittivity, and the glass is about 6. We can refer to related materials for a deeper understanding. Capacitance is a physical quantity that characterizes the ability of a capacitor to hold charge. The amount of electricity we need to increase the potential difference between the two plates of the capacitor by 1 volt is called the capacitance of the capacitor. The formula for calculating the capacitance is Cu003dεS/4πkd. According to the formula, we can know that when the capacitor is inserted into the glass, ε increases, so C also increases. The two are proportional.
