Hey

ive got a problem with a series rlc circuit

it has 2 500pF capacitors and 1 80mh Inductor and one 2.0K ohm resistor circuit has a freqency of 55 KHZ

trying to calculate total impedance im getting the wrong answer

im getting:

Xc= 1.93 kohms
Xl = 27.6 kohms

xl-xc = 25.7 kohms

so my final answer is Zt=(2.0+25.7j)

but the real answer is (2.0+16.07j)

please help haha

You need to tell us the circuit configuration, other wise how can we know what is in parallel and what is in series? Or even if the circuit can be reduced.
That is the input frequency or the natural frequency.

Please elaborate on your question/problem.
