Capacitance is a measure of how much charge a capacitor can store for a given voltage. As the voltage across a capacitor increases, the capacitance typically remains constant. However, in some cases, the capacitance may change slightly due to factors like dielectric breakdown or non-linear effects.

Why is capacitace inversely proportional to voltage?
Capacitance is not inversely proportional to voltage, rather capacitance is a measure of how much charge a capacitor can hold for a given voltage. The capacitance value remains constant regardless of the voltage applied across the capacitor. The relationship between capacitance, voltage, and charge is governed by the formula Q = CV, where Q is charge, C is capacitance, and V is voltage.
What is the relationship between capacitance and voltage in an electrical circuit?
The relationship between capacitance and voltage in an electrical circuit is that capacitance is a measure of how much charge a capacitor can store for a given voltage. In simple terms, the higher the capacitance, the more charge a capacitor can hold for a given voltage. Conversely, the higher the voltage applied to a capacitor, the more charge it can store for a given capacitance.
What is the relationship between voltage, charge, and capacitance in an electrical circuit?
In an electrical circuit, voltage is directly proportional to charge and inversely proportional to capacitance. This means that as the voltage increases, the charge stored in the capacitor also increases, while capacitance decreases. Conversely, if capacitance increases, the voltage across the capacitor decreases for a given charge.
How can we determine the capacitance of the system?
To determine the capacitance of a system, you can use the formula C Q/V, where C is the capacitance, Q is the charge stored in the system, and V is the voltage across the system. By measuring the charge and voltage, you can calculate the capacitance of the system.
What are the methods to find capacitance of a capacitor?
The capacitance of a capacitor can be found using the formula C = Q/V, where C is the capacitance, Q is the charge stored on the capacitor, and V is the voltage across the capacitor. Alternatively, capacitance can be calculated by measuring the charge stored on the capacitor and the potential difference across it. The capacitance value can also be determined by measuring the change in voltage across the capacitor in response to a known change in charge.
