WebIn quasistatic measurements, capacitance is measured directly by integrating charging current. However, CV measurements can also be made by superimposing a small sinusoidally oscillating (AC) signal on the voltage sweep and measuring the corresponding impedance directly as a function of bias voltage. (This requires the use of WebIf the AC is being generated by an electromechanical alternator, the frequency will be directly proportional to the shaft speed of the machine, and frequency could be measured simply by measuring the speed of the shaft. If frequency needs to be measured at some distance from the alternator, though, other means of measurement will be necessary.

WebAC bridge circuits can be of the “symmetrical” type where an unknown impedance is balanced by a standard impedance of similar type on the same side (top or bottom) of the bridge. Or, they can be “nonsymmetrical,” using parallel impedances to balance series impedances, or even capacitances balancing out inductances. Webzero volts. In practice, a small differential voltage must be applied to the inputs to force the output to zero. This is known as the input offset voltage, VOS.
