The frequency of an AC signal is inversely related to which property?

The frequency of an AC signal is indeed inversely related to the period. Frequency is defined as the number of cycles of a wave that occur in one second, measured in hertz (Hz). The period is the duration of one complete cycle of the wave, measured in seconds. The relationship between frequency (f) and period (T) is given by the formula:

[ f = \frac{1}{T} ]

This means that as the period increases (indicating a longer time for each cycle), the frequency decreases, and vice versa. Therefore, if the period is longer, it results in a lower frequency, illustrating their inverse relationship.

In contrast, other properties like current, voltage, and resistance do not have a direct mathematical relationship with frequency in this context, making them not applicable to the question regarding inverse relationships. Understanding this concept is foundational in AC circuit analysis and signal processing.
