The slope of an inductive reactance versus frequency graph in an inductive AC circuit is.
Correct answer: A. Constant inductance
- A. Constant inductance
- B. Decreasing inductance
- C. Increasing inductance
- D. None
Explanation
The graph of inductive reactance (XL) versus frequency (f) is a straight line passing through the origin. The slope of this line is 2πL. Since the inductance (L) of the component is constant, the slope of the graph is also constant.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
