One of these devices was suspended from a torsion fiber in an attempt to measure the effects of motion through the ether in an experiment conducted by Trouton and Noble. Hartley oscillators use one of these devices for tuning, while a Colpitt oscillator uses two of these devices to split the voltage. The first recorded example, which utilized a bottle filled with water, was invented by von Kleist

The first recorded example, which utilized a bottle filled with water, was invented by von Kleist in 1745; today, these components are used to store bits of data in DRAM. In these devices, the current leads the voltage by 90 degrees, and the reactance goes as one over the frequency. The displacement current is needed to explain the charging of, FTP, what circuit elements whose namesake property is measured in farads?
