Solution
- Alternating current (AC) is generated by most of the power stations in our country.
- It is preferred over direct current (DC) because it can be transmitted to long distances without too much loss of energy.
- Also, the other advantage of AC is that the AC voltage can be stepped up or stepped down with the help of transformers.
- The power supply generated in India has a frequency of 50 Hz.
