Customer Serviceis analogous to a capacitor with ca- pacitance C and voltage V across the capacitor. In particular, we showed how the energy stored and wasted during the process of charging the ca- pacitor are equal, respectively, to the potential energy stored and wasted during the process of filling the glass with water.
The amount of water in the bucket is analogous to the amount of charge stored in a capacitor, and the water level in the bucket is analogous to the voltage across the capacitor. The fundamental equation that describes the operation of a capacitor is i = C dv/dt. The dv/dt term is called a derivative.
Explaining a capacitor in terms of this analogy with a flow of water is more difficult; however, we will look at associating the capacitor with an unstretched membrane blocking the flow of water as is shown in Figure 1. Figure 1. A pump in a closed loop with a membrane blocking the flow. Suppose we turn on the pump.
For a capacitors are electronic the capacitance depends on the physical and geometrical proprieties of the device. It is given operationally by the ratio of the charge Q stored in the device and the voltage difference across the device ΔV. The schematic symbol of a capacitor is two parallel lines which represent the capacitor plates.
The device that does this is the capacitor. The capacitance is analogous to the capacity of the bucket, which is proportional to the diameter of the bucket (i.e., a large diameter bucket can hold a lot of water, just like a large value capacitor can store a lot of charge).
In the real world, the bucket might be leaky, and the water will slowly dribble out with the water level slowly decreasing. This is precisely what is meant by a “leaky” capacitor, that is, the charge slowly bleeds off through some internal resistance, and the voltage slowly decays back to zero.
