Question : 66

Total: 66

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

Solution:

Concept:

The period of an alternating current is the time taken for one complete cycle. It is the reciprocal of frequency:

T = \frac{1}{f}

Explanation:

We are given frequency

f = 100\text{ Hz}

Using the formula

T = \frac{1}{f}

Substitute the given value:

T = \frac{1}{100}

T = 0.01\text{ s}

Therefore, the period is

0.01\text{ seconds}

Answer:

T = 0.01\text{ s}

, which is option B.
