The slope of an inductive reactance versus frequency graph in an inductive AC circuit is.
Correct answer: A. Inductance
- A. Inductance
- B. Reactance
- C. Conductance
- D. None
Explanation
The formula for inductive reactance is XL = 2πfL. This is a linear equation of the form y = mx, where y=XL and x=f. The slope (m) of the line is therefore 2πL. The inductance (L) is proportional to the slope.

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.
