A 6.8 k
resistor, a 7 mH coil, and a 0.02
F capacitor are in parallel across a 17 kHz ac source. The coil's internal resistance, RW, is 30
. The equivalent parallel resistance, Rp(eq), is

@Mrakovic.
Can you tell me what is Q? And by using your formula I get an answer is 18660.192 but I have a confusion this answer is right or wrong.

1/(Z-30) = 1/6.8 + J*.017*0.02 + 1/(J17*7).
Now Z can be calculated in form of 1/z = x + j Y.
Rp = 1/x.
Now Z can be calculated in form of 1/z = x + j Y.
Rp = 1/x.

Consider internal resistance of coil with inductive reactance.
Z (L) =jX (L) +R (L).
And add all components in parallel now.
It's complex but you will get answer.
