ISRO Electronics & Communication (ECE) 2007 - Question 67

All ISRO Electronics & Communication (ECE) papers | ISRO Electronics & Communication (ECE) 2007

The impedance of an inductive reactance varies

  • A. Linearly with frequency
  • B. Parabolically with frequency
  • C. Exponentially with frequency
  • D. Linearly with frequency in an increasing manner

Answer: A. Linearly with frequency

Explanation: Inductive reactance is given by $X_L = 2\pi f L$. Since $X_L \propto f$, the impedance varies linearly with frequency.
