Final answer:
The correct option for the question is Option 1: Frequency, amplitude, VHF.
Step-by-step explanation:
The correct option for the question is Option 1: Frequency, amplitude, VHF.
In the context of an aircraft generator, the isolated refers to the frequency of the generator, which determines the number of cycles per second. The maximum oscillation refers to the amplitude of the oscillations, which represents the maximum distance the generator moves from its equilibrium point.
The band refers to the frequency range in which the generator operates, with VHF (Very High Frequency) being one of the options.
To determine the time for one complete cycle of 400-Hz AC power used in military aircraft, we use the relationship between frequency (f) and the period of oscillation (T), which is T = 1/f. For a 400-Hz frequency, this calculation becomes T = 1/400 s, resulting in 0.0025 seconds or 2.5 milliseconds for one complete cycle of the power.
This period of oscillation reflects how often the AC voltage completes one full sine wave cycle, which is essential for designing aircraft components that operate effectively at these frequencies.
