The rated output of a cartridge (such as 3.0 mV, or 0.5 mV) is the voltage of the output signal, usually based on the stylus tracking at a specific rate (for example, 5 cm per second). Moving coil cartridges usually have voltage output of less than 1.0 mV (although there are a few high output MC cartridges with output of 1.5 mV or so).
Updated June 23, 2016. Blood alcohol concentration (BAC) is a measurement of the percent of alcohol is in a person's bloodstream. This, rather than the exact amount of alcohol the person has consumed, will determine the effects the alcohol will have on the person's brain, body and behavior.
Variance at completion (VAC) is a comparison of the original budget at completion (BAC) and the revised forecast (EAC). A negative VAC is an indicator that the project may exceed the BAC. See all posts in our PMP Concepts Learning Series.
