for design of all electrical machines,transmission lines "form factor" is considered. form factor(R.M.S value/ Average value) of a SIN wave is 1.11(.777/.635). for making design calculation easy all the transmission ,generating voltage is multiple of 1.11( you can say 11 also).As we know Electricity generation is in SIN wave only

It isn't always. Lots of 'local' distribution networks run on either 41.6 KV or 12.5KV (in fact, those are probably the two most common distribution voltages)
Long-haul lines usually run from 350KV to upwards of one million volts, but there aren't any real 'standards' for distribution voltage.

first observe that P(avg)=V(rms)*I(rms), with I(rms)=V(rms)/R, to that end we've P(avg)=V(rms)^2/R with V(rms) laid out in each and each sub-case and R=10.0 ?, to that end: (a) V(rms)=15kV=15*10^3 V P(avg)=(15*10^3)^2/10 =22,5*10^6 W =22,5 MW skill Loss = 22,5-11 = 11,5 MW (b) V(rms)=110kV=a hundred and ten*10^3 V P(avg)=(a hundred and ten*10^3)^2/10 =1210*10^6 W =1210 MW skill Loss = 1210-11 = 1199 MW (c) for (a) skill loss share = 11,5/22,5 * a hundred% = 51.11111111...% for (b) skill loss share = 1199/1210 * a hundred% = ninety 9.09090909...% desire this helps.

Because there is term called "form factor" associated with it.
The value of form factor is 1.11
This is the starting point for answer to your question.
Thats all I know.
