Question

The magnitude of an AC voltage used in India is ............... and the frequency is...........
A. 110V, 60Hz
B. 110V, 50Hz
C. 220V, 60Hz
D. 220V, 50Hz

Answer 1

Hint:Mains electricity by nation comprises a list of nations and territories, as well as the plugs, voltages, and frequencies that they normally use to power low-voltage appliances, equipment, and lights in homes and businesses. (See industrial and multiphase power connectors and sockets for industrial machines.)

Complete step by step answer:
Voltage, frequency, and plug type are all different, though huge areas may utilise the same standards. Physical compatibility of receptacles does not guarantee voltage, frequency, or connection to earth (ground) compatibility, including plugs and cables. Older standards may still exist in some regions. For the convenience of travellers, foreign enclaves, extraterritorial government posts, or structures frequented by visitors may support plugs not typically used in the nation.

The standard voltage and frequency in India are 230 V and 50 Hz, respectively. If the normal voltage in your nation is between 220 and 240 V, you can use your electric equipment in India (as is in the UK, Europe, Australia and most of Asia and Africa). These little variations are taken into account by manufacturers. If your country's standard voltage is between 100 and 127 volts (as it is in the United States, Canada, and most South American nations), you'll need a voltage converter in India.

A combination power plug adapter/voltage converter is another option. It is not recommended to use your appliances if the frequency in India (50 Hz) differs from that in your country. However, if there is no voltage difference, you might try to use the appliance for a short period (at your own risk).

Appliances that move, rotate, or have a timer, such as clocks, shavers, and electric fan heaters, require extra caution. Check the appliance's label for confirmation. Some appliances don't require a converter at all. If the appliance's label says "INPUT: 100-240V, 50/60 Hz," it can be used in any country. Chargers for tablets/laptops, cameras, mobile phones, toothbrushes, and other electronic devices are all susceptible to this.

Hence, the correct answer is option D.
