Problem 11CQ
Can an RLC circuit have the same impedance at two different frequencies? Explain.
ANSWER:Step 1 of 2
The impedance is given by
The frequency-dependent quantities in this expression are and .
Since they enter as the difference squared, there exist two frequencies for which this difference squared is the same.
