why we step up voltage for reducing the loss, even if
voltage and current are proportional anr resistance remains
same

Answer Posted / shekhar

Rabindra for power loss we never use p=vi formula and the
logic u have given doesn't make any sense
power loss=i^2*r
that is why we step up voltage to reduce current.
While transmission we take care of current and in
distribution to consumer voltage is taken care of
