A schematic, also known as a circuit diagram, is a visual representation of an electronic circuit. It uses standardized symbols to represent electronic components and shows how these components are connected to form a circuit. Unlike a pictorial diagram, a schematic doesn''t aim to represent the physical layout of the components.
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
