Question

What is the ratio of inductive and capacitive reactance in AC circuit ?

• A. ${\omega }^{2}LC$
• B. 1
• C. zero
• D. ${\omega }^{2}L$

Answer 1

Answer: (A)

Inductive reactance, $X_L=\omega L$
Capacitrve reactance, $X_C=\frac{1}{\omega C}$
Therefore, $\frac{X_L}{X_C}=\frac{\omega L}{1/\omega C}$
= ${\omega }^{2}LC$
