What is RMS Peak value and average value?
RMS is used to determine the average power in an alternating current. Since the voltage in an A/C system oscillates between + and -, the actual average is zero. The RMS or "nominal" voltage is defined as the square root of the average value of the square of the current, and is about 70.7% of the peak value.************************************************************The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.Fo a sine wave, the r.m.s. value is 0.707 x the peak value.The average value is different; for a sine wave it is 0.636 x the peak value.
Are all resistances in series connections the same?
No, all resistances in series connections are not the same. Different value resistances can be series together. The results of the resistances in series are always the same, they are additive.
Why do you have to find RMS value?
Root mean square (average ***) voltageBecause ac (alternating current) does not warm up a lamp, heater, etc. as well as a direct current of the same value as the peak ac, we need to work out how to find the equivalent dc (direct current) voltage for the ac situation.The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.For a sine wave, the r.m.s. value is 0.707 times the peak value, or, conversely, the peak value is 1.414 times the r.m.s. value.Peak voltagePeak voltage is measured from the zero axis to the top of the curve. So, in the case of the UK mains supply, where the average r.m.s. voltage is 230 volts, Vpeak = √2 x Vrms = √2 x 230 V = 325.22 volts.Note: The average voltage is always zero.*** The average value and the r.m.s. value of a sine wave are not the same thing. The average value of a sine wave is 0.636 x the peak value.
What is link between maximum current and average current?
You are, presumably, referring to alternating current, in which case the 'maximum' current is the peak or amplitude of the waveform. The 'average' value of current is zero, because the average value of the first half of each cycle is negated by the average value over the second half of each cycle. This is why a.c. currents and voltages are always expressed in 'root-mean-square' (r.m.s.) values which is the value of an a.c. current that does the same amount of work as a given value of d.c. current. The r.m.s. value for a sinusoidal current (and voltage, as voltage and current are proportional) is 0.707 times the peak or maximum value.
What is the average value of an ac voltage that has a maximum peak voltage of 80 vac?
To get the average:Volts avg=0.637 X Vp (peak)0.637 X 80 Vp = 50.96 VavgTo get rms (root mean square):Volts rms = 0.707 X Vp (peak)0.707 X 80 Vp = 56.56 VrmsCommentIt should be pointed out that the average value, described above, is for half a cycle. The average for a complete cycle is zero.
Can different sounds be produced by sound waves with the same frequencies?
No. The frequencies determine the sound.
What will be the effect of mounting two different fm radio antennas with different frequencies on the same mast?
There will be no interference because the antennas are on different frequencies.
What are two sound waves with the same frequencies and different amplitudes?
Same pitch but with different loudness
Do all sound waves have the same wave length but different frequencies?
no
Are the speed of ultrasonic and audible sound wave same?
Traveling in the same medium, they have the same speed - just different frequencies (and wavelengths).
Average property tax rate in charlotte North Carolina?
The rate is the same, the value of the property it is applied to is different.
How does a speaker vibrate at different frequencies at the same time?
An infinite number of sounds can be mixed together into a single sound wave. The different frequencies don't matter, unless they are specific frequencies that cancel each other out. You'll notice that, even though you have only two ears, you can still hear all those sounds at the same time.
Why don't gene frequencies change from one generation to the next?
the DNA remains the same. just different parts of it get translated
Two sound waves of the same frequency can interfere with each other but two sound waves must have different frequencies in order to make beats. Why?
To alternate between constructive and destructive interference requires different frequencies.
What can you say about the speed of different colors in air?
You can that they're all identical.
How is fair value different from present value?
same
If two waves traveling at the same speed have different frequencies which wave has more energy?
Which ever is the highest frequency
