The internal resistance of a pure inductor is.
Correct answer: A. Zero
- A. Zero
- B. Infinite
- C. Finite
- D. None
Explanation
A pure or ideal inductor is a theoretical component that has only inductance and no resistance or capacitance. In this ideal model, its internal DC resistance is considered to be zero.

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.
