The basic circuit elements in A.C circuits are:
Correct answer: C. Inductor and capacitor
- A. Thermistor
- B. Inductor and resistors
- C. Inductor and capacitor
- D. All of above
Explanation
The correct option is "inductor and capacitor." In AC circuits, inductors and capacitors are the basic circuit elements due to their reactive properties, which affect the flow and distribution of alternating currents and voltages.

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.
