Assume that you have a capacitor of area 0.1 meters squared, that has plates 0.01 meters away from each other. Also, there is air between the plates. So, what will be the charge that the plates can store if it is connected to a 9V battery?
For solving this firstly, write down what we know. So, the area is 0.1 meters squared, then A = 0.1. Moreover, the plates are 0.01 meters distant from each other, so d = 0.01. Furthermore, there is air between the plates thus K is approximately 1. Also, the voltage is also given which is V =9 volts. Besides, we have to find the charge that is Q. In...
Suppose a parallel plate capacitor contains two plates with a total surface area of 100 cm2. Then what will be the capacitance in pico-farads, (pF) of the capacitor if the plate separation is 0.2 cm? and the dielectric medium is air. Solution: C = εAd , ε = 8.85 pF/m A = 100cm2 = 0.01 m2 d = 0.2 cm 0.002 m So, C = 8.85 × 10−12 × 0.01m20.002m = 44 p...
Capacitance is the capacity of a material object or device to store electric charge. It is measured by the charge in response to a difference in electric potential, expressed as the ratio of those quantities.

The capacitance of any capacitor can be either fixed or variable, depending on its usage.
The capacitance \(C\) of a capacitor is defined as the ratio of the maximum charge \(Q\) that can be stored in a capacitor to the applied voltage \(V\) across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device: \[C = \frac{Q}{V} \label{eq1}\]

Definition of Capacitance. Imagine for a moment that we have two neutrally-charged but otherwise arbitrary conductors, separated in space. From one of these conductors we remove a handful of charge (say \(-Q\)), and place it on the other conductor. Figure 2.4.1 – Charge Separated to Two Conductors
