Capacitivereactance is inversely proportional to the rate of change of input voltage applied to the capacitor.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. An antenna which is shorter than its resonant length has capacitivereactance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These have a very low radiation resistance and a high capacitivereactance, making them inefficient antennas. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Above the resonant frequency the capacitivereactance becomes the dominant part of the impedance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. An antenna shorter than a quarter wavelength presents capacitivereactance to the transmission line. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. If the tower is very short, it will have its capacitivereactance tuned out by this matching network. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The "director" element, on the other hand, being shorter than /2 has a capacitivereactance with the voltage phase lagging that of the current. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Electrical impedance is the vector sum of electrical resistance, capacitivereactance, and inductive reactance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The antenna usually acts as a capacitor, because antennas shorter than a quarter-wavelength have capacitivereactance. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Electrically short antennas have considerable capacitivereactance, so to make them resonant at the operating frequency an inductor (loading coil) is added in series with the antenna. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This allows the antenna to be made much shorter than the normal length of a quarter-wavelength, and still be resonant, by cancelling out the capacitivereactance of the short antenna. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The capacitivereactance in the bridge will exactly oppose the inductive reactance of the load when the bridge is balanced, allowing the load's resistance and reactance to be reliably determined. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Energy passing as alternating current is also lost as it travels but, since it changes direction, there is an additional loss proportional to the capacitivereactance times the current.
