Which symbol represents capacitance?

Which symbol represents capacitance?

• A. Capacitance is symbolized by C
• B. Voltage is symbolized by V
• C. Resistance is symbolized by R
• D. Current is symbolized by I

Answer: (A)

Capacitance is represented by the symbol C on circuit diagrams. Engineers use standard letters to denote different electrical quantities, which keeps reading schematics and applying formulas consistent. Capacitance describes how much charge a capacitor can store per unit voltage, and it appears in key relationships like Q = C V, with current through a changing voltage described by i = C dv/dt. The other common symbols map to their respective quantities: voltage is denoted by V, current by I, and resistance by R. Knowing these conventions makes it straightforward to identify what each symbol stands for when analyzing circuits.
