napięcie skuteczne Explanation: RMS Voltage: RMS voltage is absolutely the most common way to measure/quantify AC voltage. It is also the most useful. Because AC voltage is constantly changing and is at or near the highest and lowest points in the cycle for only a tiny fraction of the cycle, the peak voltage is not a good way to determine how much work can be done by an AC power source (e.g. your amplifier, a wall outlet in your house...). DC voltage is constant. Its voltage level can be plugged directly into the formulas for power (on the Ohm's law page) and you will get an accurate image of its ability to do work. RMS voltage will give you the same ability to predict how much work will be done by an AC voltage. The RMS voltage of a pure‡ sine wave is approximately .707*peak voltage. If you read voltage with a voltmeter you are generally given the RMS voltage of the wave form. Some meters display an 'average' voltage which is very close to RMS. When reading voltage with a voltmeter, the display indicates the RMS or average voltage not the peak or peak-peak voltage. -------------------------------------------------- Note added at 19 mins (2005-04-18 20:49:14 GMT) -------------------------------------------------- skrót pochodzi od: Root Mean Squared Voltage czyli pierwiastek kwardratowy ze średniej kwardtau napięcia albo zapisując matematycznie: =sqrt(avg(V^2)) Reference: http://www.bcae1.com/voltages.htm |
