One complete set of positive and negative value of alternating quantities is called:
Correct answer: D. Cycle
- A. Frequency
- B. Time period
- C. Amplitude
- D. Cycle
Explanation
The correct option, "cycle," refers to one complete set of positive and negative values of an alternating quantity. It represents a full oscillation or waveform, including both the positive and negative halves of the cycle.

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.
