Tuned Cct Question?

Please have a look at the attached image which is of a Parallel tuned cct.

I have a few questions regarding this cct.

1. What is the purpose of the cct? Is it some kind of filter (I.e Band Pass etc?)

2. What is the purpose of the resistor? I was under the impression that the resistor was there to allow the output to be viewed by a oscilloscope when at resonance.

Cheers in advance for any help.

Paul,

What do you think happens to the current through and the voltage across that anti-resonant circuit as you sweep through the various frequencies?

Well I would say that below resonance the voltage would be lower and also it would get lower as you go above resonance. The current will be minimum at resonance and will get higher as you go below and above resonance.

Am I along the right lines?
