What is the capacitor symbol?
Understand the Problem
The question is asking for the symbol that represents a capacitor in electrical schematics. This symbol is used in diagrams to denote where capacitors are placed in circuits.
Answer
Two parallel lines or plates. Additional arrow for variable capacitors. Curved line for polarized capacitors.
The capacitor symbol is typically drawn as two parallel lines or plates. For a variable capacitor, an additional arrow indicates the adjustable part. For polarized capacitors, one line may be curved.
Answer for screen readers
The capacitor symbol is typically drawn as two parallel lines or plates. For a variable capacitor, an additional arrow indicates the adjustable part. For polarized capacitors, one line may be curved.
More Information
In circuit diagrams, different symbols are used to indicate whether capacitors are polarized, variable, or non-polarized. Specific shapes and additional marks like arrows or curved lines indicate these attributes.
Tips
A common mistake is to incorrectly identify the polarity of capacitors. This can be avoided by carefully noting the presence of curved lines (polarized) or arrows (variable).
