The capacitor symbol consistently represents capacitors in electrical schematics and circuit designs. This symbol provides essential information about the circuit's capacitor's type, value, and polarity. Engineers and technicians can understand the capacitor's function and characteristics without physically inspecting the component.
Their symbols in circuit designs vary depending on their construction and features. In circuit diagrams, film capacitors are typically represented by a rectangle with rounded corners featuring a straight line on one end for the positive terminal.
Variable capacitors are typically depicted as a rectangle with two parallel lines, one representing the stationary plate and the other the movable plate. An arrow pointing towards the movable plate indicates that changing the plate's position alters the capacitance.
In circuit diagrams, film capacitors are typically represented by a rectangle with rounded corners featuring a straight line on one end for the positive terminal. The negative terminal of the rectangle is represented by a curved line or the absence of a line, resembling symbols used for other fixed capacitors. 1.
One of the lines may be curved for polarized capacitors, such as electrolytic capacitors, or the plus "+" symbol is used on the positive side. The symbol does not depict the actual physical layout of the component. Still, it helps understand its function - storing and releasing electrical charge - and how it is connected to the circuit.
Unlike resistors, capacitors use a wide variety of codes to describe their characteristics. Physically small capacitors are especially difficult to read, due to the limited space available for printing. The information in this article should help you read almost all modern consumer capacitors.
Capacitor
A capacitor is an electrical component that stores and releases electrical energy in a circuit. It consists of two conductive plates separated by an insulating material called a dielectric, allowing it to accumulate charge when connected to a voltage source. Capacitors play a crucial role in various electronic applications, such as filtering signals, stabilizing voltage, and timing circuits.
