As you vary the frequency, the voltage rises
As seen in the lightbulb, a voltmeter or a scope.
You can say that by changing the frequency you are sweeping the coil.
If you sweep the coil and the voltage rises very quickly you can
say this is a high Q where as a mild gradual change is a low Q
When you first tune a resonant circuit it is sometimes useful
to start with a low or medium Q and after you are happy with the
operation you can replace the componants with a higher Q for little higher performance.
The best tool is your brain the scope is not as important.
