the following is a delta connected load,connect to a 3phase 240 volt 60 supply
a-b coil Z = 12 ohm pf = .7
b-c coil z = 20 ohm pf = .8
c-a coil z = 24 ohm pf = .7
calculate total active power of the load. (answer is 7344)
now ive found the current per phase by Z X pf = A
i just have no idea ....well i forget how to add them all together to give me the total....
