for the same power.p=v*i.this is why as voltage increases current decreases

Bcs R=V/I (acc to ohm's law)

Answer / 7873269919

Because in an transformer input power is greter than the
output power or they are equal,so that if we increase the
voltage the current will decreases & vice versa.

line vltage of three phase distribution transformer is 433v and phase voltage is 250v,but we required 230v for domestic distribution,then how we reduce phase voltage of transformer
