In a certain balanced three phase system each line current is 5 a and each line voltage is 220v what is the approximate real power factor is 0.7?

1905 watt's ( the pf hasn't been indicated as leading or lagging) this is wrong. the answer is 1770 W its looking for a symplified answer if you dont know whether its leading or lagging use basic formula 220v * 5a * .7 = watts
