Understanding Peak and RMS voltages in terms of the power dissipated in a light bulb. Practical examples yields values that illustrate the accepted equation for peak voltage.
i watched 3 videos and this is the only video that i understand what is rms thank you so much ! your way of teaching with demonstration is one of best method to teach ...
i was just about to give up trying to understand this, then i decided to see this vid as a LAST chance for myself to get it and im glad i did, thank you for the great video
Thank you for your clear and succinct explanation. I think something like that was explained to us once but I really never understood it until I came upon your video.
Current in a resistor is a start-stop motion of conduction band electrons due to their collision with the rocking lattice ions, and this causes a resistor with a sinusoidal voltage applied, to produce heat. The polarity reversals of an applied sinusoidal voltage (with the direction reversals of the applied electric field) do not affect electron collisions with the lattice ions. Electrons colliding with lattice ions from either direction will continue to produce heat and there is no cancellation of the heat developed! Mathematically, the average value of a sinusoid is zero, and so, the average value of the current will also be zero. The average values cannot therefore represent the heat developed in a resistor with a sinusoidal current. A resistor cannot develop heat due to a current in one half-cycle and then cool itself by a like amount of heat during the next half-cycle! It develops heat either way whether the current is positive or negative. The lattice ions vibrate from collisions irrespective of the directions in which the electrons collide with them. Therefore, since the average value is zero, it necessitates the use of the root-mean-square values of the voltage and current to compute the power, which is a statistical measure of the magnitude of a varying quantity and is the square root of the arithmetic mean of the square of the sinusoidal function. Electrostatics and circuits belong to one science not two. To learn the operation of circuits it is instructive to understand Current, the conduction process, resistors and Voltage at the fundamental level as in the following two videos: i. ua-cam.com/video/TTtt28b1dYo/v-deo.html and ii. ua-cam.com/video/8BQM_xw2Rfo/v-deo.html It is not possible in this post to discuss in more detail average and rms values. The last frame References in video #1 lists textbook 4 which discusses in detail using a unified approach sinusoidal voltage, current, their average and root mean square values.
Mate. Legendary video! Using it with my physics class tomorrow. Thanks so much. Best explanation of Peak vs. RMS I've ever seen : )
I've been searching for this. straight to the point and well visualized. thanks!
It's really cool that you used an edison cylinder phonograph to record the audio
The best explanation of rms I ever seen, Big thanks
straight forward and simple, love u mate.
This is so much better than the other 100 other videos I have seen. Thank you bro! I actually get it now! :)

Sir, Excellent video for beginners
This is a fantastic video, the example given with the light brightness is a great way to get the point across in the most straight forward manner.
Thanks, I find it makes a really convincing demonstration in class. Thank you for your feedback.
i was just about to give up trying to understand this, then i decided to see this vid as a LAST chance for myself to get it and im glad i did, thank you for the great video
No problem, glad it helped.
Clear and intuitive explanation. Very nice approach. Thank you for sharing.
Thank you and I am glad you found it useful

Short and simple, thanks mate🔥
Glad it helped
Finialy a example that is easy to understand! Thank you!
Nice video professor 👍
Outstanding straightforward working explanation, thank you and well done sir..😊
Best explanation I've seen on youtube..👍👍👍
Very helpful video explaining RMS and Peak Voltage of Sinuodial AC compared to an equivalent DC Voltage.
great explanation!
thank you!!
you are a professional mate, thank u
LEGEND!!!!! THANK YOU SO MUCH MATE
No problem, glad you found it useful
Very clear!
you, are a legend
Awesome !.
very nice demonstration
What an awesome video, finally get it. Thank u so much
الله يباركلك💕💕
Glad it helped!
Very clear explanation.... Thanks...
You are welcome. Sorry I didn't reply earlier.
Great explanations thanks !!!
can't thank you enough
thank you very very much
W explanation
What about vpp×0.353=vrms???
Is there where 208 volts comes from? 😮
After 10 years i understood what is
RMS voltage 🤣🤣🤣 omg
"blue line is D.c.", excuse me thats yellow
