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
@Cedillallidec
6 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.

You did mention that RMS value will change per waveform used. I agree with this, however I disagree on the statement that RMS value is equivalent to DC value. For instance, a square wave with 50% duty cycle ranging from 0V-20V will have a DC of 10VDC but an RMS value of 14.14VDC. Please correct this if I am assuming a false statement.
You are not quite understanding the concept. RMS voltage is defined as the equivalent DC voltage that will dissipate the same power in the same circuit as the AC voltage under consideration. Power dissipation is calculated by P = V^2 / R. Since the circuit will be the same, we can ignore R (it will be the same for AC or DC by the definition of an equivalent circuit) so power dissipation is proportional to V^2. Since the voltage is changing in an AC system, we have to calculate the total energy dissipated in a single wave form. Let's take a 20V square wave at 75% duty cycle. V V^2 20 400 20 400 20 400 0 0 -20 400 -20 400 -20 400 0 0 Mean V^2 = 300V^2 (2400V^2 / 8) Root of Mean V^2 = 17.3V A 17.3V DC current will dissipate the same power as a 20V AC square wave at 75% duty cycle. At 50% duty cycle, the equivalent DC voltage to dissipate the same power will be 14.1V DC.
