Question

The AC produced in India changes its direction in every:

✓

Answer

$\frac{1}{100}\text{second}$

Explanation:
In India, the frequency of AC voltage is 50 Hz.
It means 50 waves will be produced in 1 s.
In one wave, the direction is changed 2 times.
Thus, in 50 waves, the direction will be altered 50 × 2 = 100 times.
i.e. the direction is changed 100 times in 1 s.
Thus the direction is changed in every $\frac{1}{100}\text{second}$
