Why does wire not have large capacitive reactance?

The same formula applies. Wires have low capacitance to their surroundings so they have high Xc. Capacitors have high capacitance in comparison so they have low Xc.

Capacitive Reactance Calculator

As a capacitor charges up in a DC circuit, the charges accumulating on the capacitor plates will begin to oppose the current flow until it reaches zero (see force between two charges).. In AC circuits, however, capacitors are constantly being charged and discharged, so this opposition to current is present at all times. We call this resistance to current flow the …

How do smaller capacitors filter out higher frequencies than larger ...

If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering high frequencies as a smaller value one.. But capacitors are not purely capacitive; ones we can practically build are also unfortunately inductive, and at some frequency the inductive behavior dominates over the …

18.5 Capacitors and Dielectrics

The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28) the size of a football field could hold a lot of charge without requiring too much work per unit charge to push the charge into the capacitor. Thus, Q would be large, and V would be small, so the capacitance C would be very large.
