The schematic symbol for a capacitor consists of two parallel lines, with a curved line in between. This curved line represents the capacitor’s plates, which are the conducting surfaces where the electric charge is stored. The parallel lines represent the terminals of the capacitor, which are used to connect it to other components in a circuit.
The graphical symbols of capacitors vividly express the structure of the component: two parallel lines signify the two plates where the dielectric is present within the capacitors, and two fine lines perpendicular to each of them represent their connection to the circuit wires. The several types of capacitors to be discussed are: 1.
Circuit diagram symbols for these capacitors depend on their manufacture and features. Variable capacitors are usually represented as a rectangle with two parallel lines and an arrow pointing toward the movable plate. One line represents the stationary plate and the other represents the mobile plate.
Polarized capacitor symbol: This symbol consists of two parallel lines with a curved line on one side, indicating the polarity of the capacitor. It is used to represent electrolytic or tantalum capacitors, which have a specific polarity and must be connected in the correct orientation.
Another typical capacitor sign is a rectangle with a straight line on one end, symbolizing the positive terminal. The rectangle's negative terminal is usually a curved line or no line. The symbol for a fixed capacitor depends on the capacitor type and the circuit diagram designer or engineer's preference. 1. Disc Ceramic Capacitors
There is, however, a common approach to representing them using a rectangle with one straight edge and one curved or absent edge. The schematic symbols used will vary based on the type of capacitor used and the preference of a designer; clear communication must be used, with added legends, for clarity.
