Working on lab report. Not really sure how to get inductance and capacitance
from the diameters of this thing (cylindric capacitor) without also knowing
the permittivity and permeability of the dielectric. I guess I could do a
rudimentary calculation with just constants, setting permeability to 1
and permittivity to the permittivity of free space instead of its actual
material? Would that be allowed in the lab report?
The manual is pretty explicit that we use L and C to calculate other values
and then compare them to the experimentally determined values. But then the
last part of the analysis is to then use the experimentally determined vals
to find L and C.
Alright, since I'm using feels as a way to get this off my chest without
bugging my lab partner. Here we go.
Part 1 calls for calculating L and C from the diameters of the inner and
outer conductors. They didn't outline a method to do this, just said it's
in any E&M textbook. Fair enough, this is a third year lab, we should be
expected to do our own math. So I used two different textbooks because
fuck yeah, libretexts! Anyway, textbooks generally agree that you need
the permeability and permittivity for those, unless you wanna go the Q/V
route for capacitance. But we didn't measure the potential difference across
the inner and outer conductor (not possible in our case, cable) so we can't
do that.
Ending this right now to work. Fuck it why not. Worst case scenario we get
marks off.
