The derived SI unit of capacitance, defined as the capacitance in
a capacitor that, if charged to 1 C, has a potential difference of
1 V; thus, it has units of C/V.
The charge Q equired to deposit or liberate a mass m is
proportional to the charge z of the ion, the mass, and
inversely proprtional to the relative ionic mass M; mathematically,
One of the first truly relativistic experiments, intended to
measure the speed of light. Light is passed through a spinning
cogwheel driven by running water, is reflected off a distant
mirror, and then passed back through the spinning cogwheel.
When the rate of running water (and thus the spinning of the
cogwheel) is synchronized so that the returning pulses are
eclipsed, c can be calculated.
