Thanks @d4rk3n3mi3 for the insight. The question has been answered now. You actually made it clear by making a reference to the effects of frequency regulation. Frequency must be monitored and regulated to avoid system collapse. There are two different frequencies, 50Hhz and 60Hz.
In the UK, most of Europe, Africa, Australia, Southern South America, most of Asia, and Russia, the frequency of the alternating current in household electrical outlets is 50 Hz .
In North America and parts of Japan, on the other hand, a standard frequency of 60 Hz is used.
Thanks once again! I am following you for more educative posts.
