Hi I am new to electric circuits and everything but I have a test coming up that covers this. In a series AC circuit, XL = 2350 ohms, C = 0.005 µF, and R = 500 Ω. What is the impedance at resonance? I would just really like to know how to solve this. Thank you!
At resonance the capacitive reactance cancels the inductive reactance so the only impedance left is the resistance, as noted by the previous posters.
well I also need help with two more questions: A 10 mH coil has a resistance of 100 ohms. At what frequency does XL = R ? When observing a 500 KHz square wave with an oscilloscope, what period would you expect to see? (For a full cycle)
I am sorry. I just don't even know how to work those problems out. I have been searching for information and I am still lost so I thought it would be better to ask people who know for an explanation.
When I was in school, the teacher was supposed to know..... or use Google as somebody else suggested.
Hello, A lot of the answers can be found using the AC book of this site: http://www.allaboutcircuits.com/vol_2/index.html Bertus
