Hi!
I'm having problem solving an old exam question, and would really like som help with it. The problem is about a parallel RLC circuit. I've done an expert drawing of the circuit in paint (okay, it's horrible, but at least you'll understand, I hope...).
The question is: Calculate the resonance frequency and Zin (at resonance).
I've calculated Zin = [ (1/(jwL+R1)) + 1/R2 + jwC ]^1 (you may double check it to make sure it's correct)
But where do I go from there? How do I get rid of j to calculate Zin? How do I find the frequency?
