frequency
- B✓ Correct Option
amplitude
- C
phase
- D
wavelength
Detailed Technical Solution & Explanation
The maximum instantaneous value attained by an alternating sinusoidal voltage or current during one complete cycle, measured from the zero reference level, is called its amplitude (or peak value ).
Option Analysis:
•
Option A (frequency): Incorrect. Frequency is the number of cycles completed per second (in Hertz).
•
Option B (amplitude): Correct. Amplitude is the peak magnitude of the AC wave.
•
Option C (phase): Incorrect. Phase defines the angular fractional part of a period elapsed.
•
Option D (wavelength): Incorrect. Wavelength is the physical spatial distance spanned by one cycle.
