Question

What is meant by 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?

thanks for fol-lowing ​

Answer 1

Answer:

In India, frequency of AC is 50Hz , i.e. 50 cycles per second. When compared to direct current, alternating current is regarded to be more advantageous for long-distance transmission of electric energy since it can be transmitted over long distances to distant locations with little loss of electric power.

Answer 2

Answer:

any member of a class of words that typically can be combined with determiners (see DETERMINER sense b) to serve as the subject of a verb, can be interpreted as singular or plural, can be replaced with a pronoun, and refer to an entity, quality, state, action, or concept
