Question

Which of the following statements is not true for electric energy in ac form compared to that in dc form?

Options

• Production of ac is economical.

• ас сan be easily and efficiently converted from one voltage to the other.

• ас can be transmitted economically over long distances.

• ac is less dangerous.

Answer 1

ac is less dangerous.

Explanation:

AC (Alternating Current) has several practical advantages over DC (Direct Current). Easy voltage transformation using transformers, Efficient long-distance transmission, Economical generation. However, safety depends on magnitude and conditions, not simply AC vs DC. AC generators are simpler and cheaper compared to DC generators. Transformers work only with AC, allowing efficient voltage stepping up/down. High-voltage AC transmission reduces power loss (I²R losses). AC can be more dangerous than DC at the same voltage.
