Your answer: —  Â·  Correct: A
Explanation

In India, the standard distribution of electricity for domestic purposes is 220 V at a frequency of 50 Hz. The domestic power supply is delivered through a mains system consisting of a live wire and a neutral wire, where the potential difference between them is maintained at 220 V. While some sources mention 230 V as a common household supply, the standard regulatory and textbook reference for the potential difference in the country remains 220 V [1]. The frequency of the alternating current (AC) is standardized at 50 cycles per second (50 Hz) [1]. This differs from countries like the USA, which typically use a 110 V and 60 Hz standard. The 50 Hz frequency is also the standard for high-voltage and extra-high-voltage transmission lines across the Indian electrical grid.
