Perhaps a defective voltage regulator- not regulating voltage
Perhaps a defective gauge-
With an unknown voltage you should start out with the highest voltage setting on the meter. Doing this reduces the risk of "pegging" out the needle on an analog gauge or overloading the input of a DMM. Most DMM's are auto-ranging though.
maximum or peak value
Remington Model 11-48 (Highest value) Made from 1949 to 1968: 425,000 were made. $300 for all gauges except the 28 gauge. 300 percent for the 28 gauge.
300 or so
New in the box - $500-600.
The rated voltage of a generator decreases due to many causes such as armature reaction, overloading of the generator and AVR failure/ weak excitation voltage.
made in Italy in the early 1980's, Highest value I have seen is 175.00,but low is 50.00.
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".
For any value turn the multimeter to the highest scale in the value that you are measuring. By doing this you will not overload the meter by using a lower scale to measure a higher value.
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
Voltage amplitude is the maximum value of a voltage.
The RMS value of an AC voltage is VRMS = VPEAK / sqrt(2), where VPEAK = the voltage peak to neutral.AnswerThe average value of a sinusoidal a.c. voltage is zero.
