उत्तर
Domestic power supply in India is 220 V, 50 Hz.
Explanation:
The government of India has established the standard voltage and frequency of alternating current supply in India to 220 V and 50Hz, respectively, because the main issue when transmitting power from a power plant is reducing transmission losses. The current value should be low and the potential difference (voltage) should be high for this reason. At 50 Hz/60 Hz frequency, losses are also low.
