Answer / atul

actully in a transmission line since wattage or you can say
power is current x voltage.it has to be constant so if
voltage goes high current has to get low to keep power
constant.

Answer / karthik

V=IxR
this is ohm's law.According to this the current in a line
is directly propotional to the voltage across the line.But
these two are equal only when satisfying a costraint (i.e)
according to the resistance.The value of any two parameters
are maintained a constant and the third is varied.

In a transmission line the impedance is very high,and so to
maintain the voltage at a constant value the current has to
be less.In this case the line impedance is constant,and
voltage has to be maintained constant.So current is varied.

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
