Question

The alternating current produced in India changes its direction every ______.

Options

• 100 seconds

• 1/10 second

• 1/100 second

• 50 seconds

Answer 1

The alternating current produced in India changes its direction every 1/100 second.

Explanation:

In India, the frequency of alternating current (A.C.) is 50 Hz, which means it completes 50 cycles in one second. Since the current changes its direction twice in each cycle, it changes direction 100 times per second.

Therefore, the time interval between successive changes in direction is:

\[ t=\frac{1}{2\times50}\]

\[=\frac{1}{100}\text{ second}\]
