wisdomsearch said:Iam aware of the equation.I was actually looking for an explanation not mathematical to understand the logic behind the decrease in the capacitance with the increase in frequency.I have made capacitor measurements and observed the behaviour in the similar manner . Now i need to understand the theory relating to the inverse relationship between the capacitance and the frequency measurements.
Capacitance is a measure of an object's ability to store electrical charge. It is represented by the symbol C and measured in units of farads (F).
As frequency increases, the reactance of a capacitor decreases, leading to an increase in capacitance. This is because at higher frequencies, the capacitor's plates have less time to charge and discharge, resulting in a higher effective capacitance.
The capacitance of a capacitor is directly proportional to the voltage applied to it. This means that as the voltage increases, so does the amount of charge that can be stored in the capacitor.
Capacitance plays a crucial role in the functioning of electronic circuits. It can be used to filter out unwanted frequencies, store energy, and control the timing of signals. High capacitance can also lead to unwanted effects such as signal distortion and voltage drops.
The type and material of the capacitor, its physical dimensions, and the dielectric material used can all affect the capacitance vs frequency and voltage relationship. Other factors such as temperature, humidity, and aging can also have an impact on the performance of a capacitor.
