Abstract
A meter for measuring the root-mean-squared potential of an AC signal characterized by a frequency f is disclosed. The meter includes first and second capacitors. The AC signal is applied to the first capacitor, which includes first and second plates separated by a distance that depends on the root-mean-squared potential of the AC signal, but not on changes in the AC signal that occur over a time of 1/f. The second capacitor has first and second plates separated by a distance that depends on the separation of the first and second plates in the first capacitor. A detection circuit measures the capacitance of the second capacitor. The first plate of the first capacitor is preferably connected to the first plate of the second capacitor by a non-conducting mechanical link.
