u just have 2 find the apparent power and average power ...u have been given a circuit having L & C...first u have to find its impedances then find the S and P.....the formula for S is S=1/2 Vm Im..........and for P=1/2 Vm Im Cos (phi).....thats it....i have tried by this but i didnt get the correct answer.........

Your naswers should be 676VA at an angle of 58.16 degrees. PF=52%, Power = 357 watts. Now, what have you done so far?

Hope this helps.
