MCQ
The $AC$ produced in India changes its direction in every:
- ✓$\frac{1}{100}\text{second}$
- B$100$ second
- C$50$ second
- DNone of these
✓
Answer
Correct option: A.
$\frac{1}{100}\text{second}$
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 $50 \times 2 = 100$ times.
i.e. the direction is changed $100$ times in $1 s.$
Thus the direction is changed in every $\frac{1}{100}\text{second}$
