Identify the factor on which mutual inductance does not depend:
Correct answer: C. Reciprocity
- A. Relative orientation
- B. Relative separation of two coils
- C. Reciprocity
- D. Permeability of the core material
Explanation
The mutual inductance of two coils is the property of their combination. It does not matter which one of them functions as the primary or secondary coil. Hence, mutual inductance does not depend on reciprocity.

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.
