Hi,
I have a question which i can't solve. "Suppose that we connect a resistor of 25 Ohms, capacitor of 0.002µf, and a coil of 7,7 µH in parallel. We operate the circuit at 2 MHZ. What's the complex impedance?"
a) 8.1 + j22
b) 8.1 - j22
c) 22 + j8.1
d) 22- j8.1
So my reasoning is that the answer would be:
Z = R + (XL + Xc)
This gives : 25 + (j96.76 - j39.79) = 25 + j56.97
but this is not in one of the answers. What am I missing?
Thank you!
