What is the voltage of the electricity that is generally supplied to a house ?

Question

Verified by Toppr

Answer 1

Worldwide, many different mains power systems are found for the operation of household and light commercial electrical appliances and lighting. The different systems are primarily characterized by the following.

Voltage
Frequency
Plugs and sockets (receptacles or outlets)
Earthing system (grounding)
Protection against overcurrent damage (e.g., due to short circuit), electric shock, and fire hazards.
Parameter tolerances.
All these parameters vary among regions. The voltages are generally in the range 100 to 240 V. The two commonly used frequencies are 50 and 60 Hz. Single-phase or three-phase power is most commonly used today.
In India, a voltage of nearly 220 volts and a frequency of 50 cycles per second is used.
Hence correct option is option C
