What are the two main applications of AC from the following options, along with a detailed explanation?

  1. Direct, Pulsating
  2. Electric, Magnetic
  3. Power, Information
  4. Static, Dynamic

Answer – C. Power, Information


A detailed solution to the question of the two main applications of AC is provided here. 

Alternating current is mostly employed in the transportation and electricity generating industries. In actuality, AC powers practically all homes worldwide. Due to higher hazards of starting a fire, higher costs, and problems using transformers to convert high voltage and low current to low voltage and high current, DC is typically not employed for these applications.

When supplying electric motors, a machine that transforms electrical energy into mechanical energy, AC is also the more widely used current. Refrigerators, dishwashers, garbage disposals, and toasters are a few common domestic appliances that depend on this.

The main disadvantage of employing DC is that it starts to degrade over distance. Because it will decrease as the distance increases, the power from a DC source is unsuitable for long distances. With AC, this is not the case. It is hence trustworthy for transmission.

Hence, Option (C) is the correct answer.
