Answer / wareagle

You need to remember that you are transmitting watts or
kwh's and not amps. The amperage is directly related to the
load that the customer requires. According to Ohm's Law
I = E/R or watts = Volts x Amps or Amps = watts/volts.
Using a higher voltage allow you to transmit a larger amount
of watts with lower amperage and thus less voltage drop and
less losses.

Answer / kartik

First thing primary transmission for long line,voltage is
more like 330 kv.now ohm law is for resistive load or
inductive load so transformer have primary winding and
secondary winding as per requirement

is the power of a single phase induction motor(Fans) is constant under varying speeds?
