Question

What is the meaning of the term ‘frequency’ of an alternating current? What is its value
in India? Why is an alternating current considered to be advantageous over direct
current for long-range transmission of electric energy?

Answer 1

Explanation:

Alternating current (ac) frequency is the number of cycles per second in an ac sine wave. Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second.
