The above mentioned answer is wrong.Plz do remember that at any condition the power consumes by an equipment will not change from its designed value.
If you are operating a system at reduced voltage then to meet with the power requirement it will consume more current, rather than operate at less power.
So if the voltage is reduced by half, the current has to increase accordingly.
V*I = P;then 230*I = 200;I = .87A.
for V = 115 then current = 1.732A.
