The frequency of alternating current (a.c.) supply in India is
(a) 0 Hz
(b) 50 Hz
(c) 60 Hz
(d) 100 Hz
Answers
Answer:
50 Hz
Explanation:
The frequency of ac mains in India is (b) 50 c/s or Hz. The frequency as well as voltage varies from one country to another. The most efficient one is a combination of 60 Hz and 220 V. 50 Hz or 60 Hz is the optimum frequency that helps in maintaining the transmission losses to a tolerable limit.
The frequency of alternating current (a.c.) supply in India is 50 Hz
Explanation:
The power supply rule of India states that only 220-250 volts can be used along with a frequency of 50 Hz. It is because the temperature in India is high and the high frequency can totally heat up the wiring in electricity. While the temperature in the north of India is low but we cannot change the frequency as it will need expensive electrical equipment. So, the frequency of ac supply is 50 Hz in India because of its cost-efficiency.
