so the reason why alternating current is used to deliver energy to households is because for a given wire, the voltage drop is always less with ac rather than dc right?(adsbygoogle = window.adsbygoogle || []).push({});

but when i calculate the voltage drop it coumes out to be the same!

v=IR

R=P(length of wire)/(cross section area of wire)

i see no reason why an alternating current would drop less

is there an equation i am missing?
