In a power transmission there is a need for step up and step down the voltage for a certain distance. So we cant use dc for a particular distance.
AnswerD.C. transmission is used for long-range extra-high voltage transmission, for under-sea high-voltage transmission, and for international 'links'. The equipment for achieving these voltages is far more complicated/expensive compared with Transformers, making short distance d.c. transmission uneconomical.

How is Bluetooth used?
Bluetooth provides an easier method of data transmission in short range distance.
Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
What do they measure distance in Europe?
Mostly with kilometres, though miles are also used in Britain and Ireland in particular.
What is the equation used to calculate the distance something travels?
The equation used to calculate the distance something travels is given below . we know, speed = distance /time . distance = speed X time in meters /km /or any other unit of length.
Where distance relay is used?
Distance relay is primarily used in electrical power systems for protecting transmission lines from faults. It measures the impedance of the line, which allows it to determine the distance to the fault location. This type of relay is essential for ensuring the reliability and safety of power distribution by enabling timely disconnection of faulty sections. It is commonly utilized in substations and along transmission corridors.

Why area below the distance-time graph is used to calculate speed?
That's not correct. If you have a graph of distance as a function of time, the speed is the slope of the graph.
