The relationship between frequency and period is described how?

The correct relationship between frequency and period is defined by the equation that states the period is equal to the inverse of frequency. Specifically, the period (often represented as T) is the duration of one complete cycle of a periodic wave, while frequency (represented as f) indicates how many cycles occur in one second. The mathematical relationship is given by T = 1/f, which aligns with the choice identified as correct.

Understanding this relationship is crucial in various applications of electrical systems, as it helps in the analysis of alternating current (AC) signals, radio frequencies, and other oscillatory contexts. The higher the frequency of a signal, the shorter its period, indicating a direct inverse relationship. Thus, if frequency increases, the period decreases and vice versa. This foundational concept is essential for anyone working with electrical systems and signals to ensure proper functioning and troubleshooting.
