Calculating Apparent Power, Average Power, and Power Factor in AC Circuits

[mohamen]

ac impedance ...find power

this is the circuit...attached...i have to find appartent power ( S) , Average Power (P) and power factor (p)...i have tried this question a lot times but every time i get incorrect result ...please solve this question...

Thanks

Please show us what you have tried.

What are the definitions of the quantities you need to find?

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 I am Cos (phi)...thats it...i have tried by this but i didnt get the correct answer...

You need to show us what you have tried, that way we can help you find your errors.

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.
