RLC circuit close to resonance

[Ghost101]

Hi!

Recently I did an experiment of an RLC circuit nearing resonance, and I found a substantial amount of loss of both current and voltage (30%). (More so than a different kind of AC circuit)



My question is, why is this so? Or is this just a coincidence/human error?



Some of the factors affecting accuracy that I listed are common occurance in any circuit;

-Human Error.
-Tolerance in components.
-Inaccuracies in the measurement equipment.

Am I missing something significant?

Thanks in advance!

Are you refering to a series RLC circuit?

Remember that a circuit at resonance frequency experiences minimum impeadance. (it becomes purely resisitive)

This doesn't seem to make sense in my mind because as a circuit nears resonance the overall impeadance is decreasing, so one would expect the current to increase.

Hopefully others can shed light on the subject as well!
