Answer / javed

dc is more aquirate than ac because in dc there is no
charging current,less losses,no corrona or skin effect but
initial cost is much more than ac

Answer / rakesh

in case of overhead lines AC is economical for distance less than 700km.for greater than 700km DC is economical

Answer / ilaya

dc transmission is easy.but it costwies greater than the ac
transmission line.bcoz auxillary equipment need
(converter,inverter).
incase of ac transmission line economic than the dc t/m
line.but it complicate than the dc t/m line.becoz here
3wire or 4wire t/m line.
we are consider in now a days,the t/m line should be cost
effective.so we are used ac t/m line in now a days.

Answer / ifeanyi orakwe

Both forms of electricity have their specific applications,
and have their own advantages as well. However in terms of
transmission generally, I think AC is better; since we can
transform the voltage levels, we can minimize losses in
transmission, thereby maintaining good transmission
efficiency generally.
I do not think it is easy changing the voltage levels of a
DC system, except for the use of potentiometers, which
enable losses on the DC network.
Or do you know of any other means of changing the voltage
levels of the DC network?

Answer / yuvaraj.s

A.C IS THE BEST.
BECAUSE VOLTAGE STEP UP OR STEPDOWN IS EASY TO COMPARED IN
D.C SUPPLY.
IN DC SUPPLY APPLIED IN 440V BATTERY ARRANGED IS VERY
COMPLECATED & TRANSMISSION FOR ONEPLACE TO ANOTHERPLACE
ALSO.

Answer / rakeshsingh41

dc transmiission is easy but it is not effective
comparision to ac.

Answer / av

Please! Only AC is the good answer.
If you look from the high-voltage line (kV), it's the AC we
use and is AC 3 phases (shift 120° each other). From math
perspective, we can send much more power by using a
"smal" (let's say 1 inch) cable.
It's easier to transforme AC to DC. From DC to AC, you will
need more sophisticate hardware (like microControler) to
have a beautiful sin signal of AC.
AC is easier to transform to any level of voltage we want.
The DC, there is more lost because the line has a resistant
and bcause the voltage is always stable, well there are
power lost from P=V*V / R. The AC is less than that.

Answer / jaswinder

AC is Cheaper than DC because to convert AC to DC and DC to
AC converter and inverter are req at sending and receiving
end station respt.

Answer / ss

from my knowledge dc. because ac have three wires cost is
high,losses is more
