An alternating current with a frequency of 100HZ has a period of

The period of an alternating current (AC) is the time it takes for one complete cycle of the current. In other words, it is the time taken for the current to change direction and then return to its original direction. The period is usually measured in seconds. The frequency of an AC is the number of complete cycles of the current that occur per second. The unit of frequency is Hertz (Hz), which means cycles per second. The relationship between frequency and period can be expressed by the formula: Period (in seconds) = 1 / Frequency (in Hertz) If an alternating current has a frequency of 100 Hz, we can use the above formula to find its period as follows: Period = 1 / 100 = 0.01 seconds Therefore, the period of an alternating current with a frequency of 100 Hz is 0.01 seconds. So, the answer is 0.01sec.
