Capacitance of a single straight wire
In other words, an isolated conducting wire would have zero capacitance. In practice there will be objects at various distances from the wire, and the charged wire will induce charges on these objects, so the system''s capacitance, though hard to calculate, will not actually be zero (when it can be defined at all). Hope this helps.
Calculating the parasitic inductance of a capacitor
$begingroup$ @Shocked The loop is a real thing: Current enters your cap through one lead, then goes through it along its internal electrodes and through the dielectric, and finally out the other lead (usually close by the first lead). So there is a loop area spanned by these "waypoints". The smaller this loop (the smaller the capacitor …

Introduction to Capacitors, Capacitance and Charge
A capacitor is constructed from two conductive metal plates 30cm x 50cm which are spaced 6mm apart from each other, and uses dry air as its only dielectric material. Calculate the capacitance of the capacitor. Then the value of the capacitor consisting of two plates separated by air is calculated as 0.221nF, or 221pF.
3.5: RC Circuits
Think about the capacitor that cutting a wire creates: It is the thickness of the wire (very thin), and is typically separated by a very large distance. Using the parallel-plate case as a model, this results in a very small capacitance, which means that for the voltage supplied the amount of charge required to "fully charge" it is very small.
