@@el_darkstar well, take your EE studies seriously. It is now become an expectation across the electrical engineering field to take the fundamentals of engineer exam, making you EIT-certified by the time you graduate.

I have been studying very thoroughly over the last year and still have another six months to go, focusing on every detail of Network Theory. Btw, RMS was not even mentioned during my network theory course. Never enroll in an important course with an incompetent professor

Good show! It might help to mention that the reason for taking the squares of the values is to eliminate the negative numbers from the negative half of the cycle, otherwise they would cancel themselves out in the mean or average. 20+10+0+(-10)+(-20)=0 /5 =0
@Cedillallidec6 жыл бұрын
Actually the reason for squaring the values is not to eliminate negative numbers. It is done because of the equation for power in electric circuits. Vrms is defined as the equivalent DC voltage that dissipates power at the same rate as the AC peak-peak voltage on the same circuit. Remembering our basic formulae for electric circuits: P = V * I and I = V/R, we can rearrange for power to be determined as P = V^2 / R. So what you are looking for is: "what is the average squared voltage through my circuit in AC, and what DC voltage would produce the same average squared voltage." (Since R will be the same by definition for both DC and AC power dissipation.) In this example, the average squared voltage for 20V peak-peak is calculated to be 200 V^2 . So a DC voltage of 14.14V would produce the same average squared voltage of 200V^2 and therefore dissipate exactly the same power as 20 V p-p AC. Vrms is useful for calculating power consumption of AC appliances, which is why we use it. The squaring and subsequent square root has nothing to do with eliminating negative numbers from the calculation. It is a necessary step in defining the equivalent DC voltage the dissipates power at the rate of P = V^2/R. If we lived in a different universe where power dissipated with voltage to the third power , then we would calculate the "cubic root mean cube Voltage" as a handy number to determine equivalent power dissipation.

@majorpygge-phartt26437 ай бұрын
Hi, from England, UK. The sine waveform is normally used for basic ac calculations because that's what is supplied from the mains. And RMS voltage is normally used for stating ac voltages with a sine waveform because way back in past someone carried out an experiment with an electric fire element and they found that they got the same heat, and therefore the same power dissipation with the same applied RMS ac voltage as the dc supply, i.e., A 1Kw 240 volt fire element will dissipate 1Kw whether it's supplied with 240 volts ac RMS sine wave or 240 volts dc. And the term for calculating the values of different ac waveforms is the crest factor, which for a sine wave is 1.414, whereas other waveform have other figures, and just to complicate things a bit more, some ac waveforms have TWO different crest factors, that's something I learnt from working on the old type analogue TV sets with the old cathode ray tube, where some of the waveforms produced by the various circuits will give a different voltage when rectified to dc for each polarity, i.e., if you rectify it to positive it will give a different dc voltage than what you would get if you rectify it to negative, and this was often used by TV manufacturers to give different voltages of either polarity. And ac calculations get much more complex when you use reactive loads like those which are inductive or capacitive, then there's all manner of complex advanced maths involved, so you need to be good with maths!

Another way to calculate Vrms is to divide Vmax by sqrt(2) since 0.7071~1/sqrt(2). I find this way easier to remember (Ie. Vrms = Vmax/sqrt(2) )

You would be hard pressed to find a more accurate description and explanation of RMS. Back when I was teaching industrial electronics I presented it exactly like Gaurav did except in reverse. In other words I discussed RMS's relationship to a steady state DC and then gave the students the formulas. BTW for those curious about rectified but unfiltered Pulsating DC the formula to find RMS or Peak are identical to that of sinusoidal AC. In a rectified (Full-Wave Only) 60Hz waveform the voltage or current swings from zero to peak and back to zero but does not cross through zero and reverse direction. Instead it swings back up to peak and down to zero repeatedly. A 60Hz sine-wave rectified to full wave will produce a frequency of 120Hz but frequency is not pertinent to RMS values, so the formula still holds true. Note: RMS calculations won't hold true for 1/2 wave rectification because 1/2 wave rectification creates a dead time of 1/2 of the waveform. A frequency counter or scope will measure a 1/2 wave rectified 60Hz AC waveform as pulsating 60Hz DC. Wakodahatchee Chris
