No if copper is 0.5 ohm then aluminum is 1 ohm offer higher resistance for same size of wire Current handling capacity depends on wire cross sectional area not on resistance Resistance is consider for ohmic losses Hope it helps #electrogyan
@@ELECTROGYAN ok so if am rewinding a 5kw transformer with 7 gauge copper at 240 turn I should use 5 gauge aluminum to handle the same amount of current as copper for same temperature
