The relationship between the charge stored on a capacitor and the potential difference across its plates is that the charge stored on the capacitor is directly proportional to the potential difference across its plates. This relationship is described by the formula Q CV, where Q is the charge stored on the capacitor, C is the capacitance of the capacitor, and V is the potential difference across the plates.
When capacitors are connected in series, their total capacitance decreases. This is because the total capacitance is inversely proportional to the sum of the reciprocals of the individual capacitances. The voltage across each capacitor remains the same.
The capacitance doesn't depend on the charge stored in it. The capacitor has the same capacitance whether it's charged by a DC and just holding it, or in an AC circuit where the charge on it keeps changing and reversing, or in a box on the shelf connected to nothing and not charged at all.
When two or more capacitors are connected in parallel across a potential difference, the total capacitance increases. This is because the equivalent capacitance of capacitors in parallel is the sum of their individual capacitances.
When a parallel plate capacitor is connected to a battery, the voltage across the capacitor increases as it charges. The battery provides a potential difference that causes charges to accumulate on the plates, leading to an increase in voltage until the capacitor is fully charged.
When capacitors are connected in parallel, the equivalent capacitance is the sum of the individual capacitances. When capacitors are connected in series, the equivalent capacitance is the reciprocal of the sum of the reciprocals of the individual capacitances.

When capacitors are connected in parallel, the total capacitance in the circuit in which they are connected is the sum of both capacitances. Capacitors in parallel add like resistors in series, while capacitors in series add like resistors in parallel.
When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances. In this case, with three 30 micro-farad capacitors connected in parallel, the total capacitance would be 3 times 30 micro-farads, which equals 90 micro-farads. This is because parallel connections provide multiple pathways for charge to flow, effectively increasing the total capacitance.
For capacitors connected in parallel the total capacitance is the sum of all the individual capacitances. The total capacitance of the circuit may by calculated using the formula: where all capacitances are in the same units.
The units of capacitance are called farads. A one farad capacitor is a capacitor with 1 volt potential difference with 1 coulomb of charge on the capacitor, C = Q/V or Q=CV So the charge held on your capacitor is Q = CV = 9Volts * 0.40*10-6Farads=3.6*10-6 Coulombs
To achieve greater capacitance, two capacitors should be connected in parallel. In a parallel configuration, the total capacitance is the sum of the individual capacitances, allowing the circuit to store more charge. This setup ensures that the voltage across each capacitor remains the same while effectively increasing the overall capacitance.
A tapped capacitor is a type of capacitor that has one or more additional terminals (taps) connected to points along its dielectric material, allowing for multiple capacitance values from a single component. This design is commonly used in applications where variable capacitance is needed, such as in tuning circuits and filter applications. The taps enable flexibility in circuit design, making it easier to adjust capacitance without needing multiple discrete capacitors.
Since the total capacitance for capacitors in parallel is the sum of the individual capacitances. I'm sure that you can work it out for yourself!
When two or more capacitors are connected in parallel across a potential difference, the total capacitance increases. This is because the equivalent capacitance of capacitors in parallel is the sum of their individual capacitances.
It's the same formula as resistors in parallel: C = C1xC2/(C1+C2) C= 20 x 50 / 70 = 14.3 uF.
