Different stages of power production and transmission are given. Arrange them in the proper sequence.
a) Distribution transformer reduces the voltage from 11 kV to 220 V.
b) Voltage is reduced from 220 kV to 66 kV supply electricity to large-scale industries.
c) Turbine is rotated to operate the generator.
d) Transmission of electricity at the power stations starts at 220 kV.
e) Electricity is produced at 11 kV.
f) Domestic consumers get electricity.

The correct option is B c, e, d, b, a, f
Electric power is generated by rotating the turbine. Electric power is generated at the generating station at 11 kV as these stations are located at very far off places from areas where it is to be used. At grid sub-station (power station), this voltage is stepped up from 11 kV to 220 kV to minimize the loss of energy in transmission line wires.
At main sub-station this voltage is stepped down from 220 kV to 66 kV for large-scale industries and to 33 kV / 11 kV for small-scale industries. At distribution transformer or city sub-station, it is further stepped down from 11 kV to 220 V for supply to houses for consumers.
Hence the proper sequence is c, e, d, b, a, f.
