Question
What letter is used to represent reactance?
Answer Options
- A) Z
- B) X
- C) B
- D) Y
Correct Answer: B
Explanation
In electrical and electronic circuit theory, standardized letters are used to represent various electrical quantities. Resistance is represented by R, inductance by L, and capacitance by C.
Reactance, the opposition to AC flow caused by inductors and capacitors, is represented by the letter X. Inductive reactance is X_L, and capacitive reactance is X_C. The total opposition, Impedance, is represented by Z (Z = R \pm jX), while the reciprocal, Admittance, is Y (Y = 1/Z).
