I have a problem that asks about the movement of the second plate of a
capacitor in order to change the resonant frequency by 10 ppm in an LC
circuit. I am getting stuck in terminology.
Here is the information given:
Area of each capacitor plate (one attached to solid nonmoving post while
other can move small distances perpendicular to the plates)
..01 m^2
Initial plate separation
100 micometers
Inductance
120 nH
I have found the initial capacitance and frequency, but the second part of
the question says "How far must the second plate move to change the resonant
frequency by 10ppm". I am not entirely sure what this question is asking
for. Where does ppm fit into any of the calculations. I don't want
answers, but I would appreciate if somebody can translate the question into
something I might understand.
