In DC system there is no power factor, so we can find the
current easily.

Power=voltage x current

current(I)=power/voltage

Answer / gaurav naik

Since here ther is no power factor into play
we can make use of ohms law

R=V/I

or

P=I^2*R

Answer / chennu

in dc supply we can find by relation
i=voltage/resistance
in any signal we can find by using fourier analysis
we can find constant A0
which gives the dc load component
