What is the relation between the period and frequency of an alternating current?

The period and frequency of an alternating current are inversely proportional.

An alternating current (AC) is a type of electrical current that changes direction periodically. The period of an AC is the time taken for one complete cycle of the current, while the frequency is the number of cycles per second. The period and frequency are related by the equation f=1/T, where f is the frequency and T is the period.

Since frequency is the number of cycles per second, it is measured in Hertz (Hz). The period, on the other hand, is measured in seconds. Therefore, if the frequency of an AC is high, the period will be low, and vice versa. This means that the period and frequency of an AC are inversely proportional to each other.

The relationship between period and frequency is important in the study of AC circuits. For example, in a circuit with a capacitor or an inductor, the period and frequency of the AC will affect the behaviour of the circuit. The period and frequency can also be used to calculate other parameters of the AC, such as the amplitude and phase.

In summary, the period and frequency of an AC are inversely proportional to each other. This relationship is important in the study of AC circuits and can be used to calculate other parameters of the AC.
