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.

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.
What kind of transmission sensor is on a 97 Taurus?
AnswerThere are two sensors on this transmission. One is the speed sensor. The other is used by the computer to tell what gear it is in and if the transmission is slipping. I hope this helps you.See "Related Questions" below for more
