But vrms=v/root2 but why have you written v/2????please tell
Vav of square wave should be 0 because it is symmetric, right? And form factor of square wave should be infinite.
thinking the same
But we all know that for half wave rectifier , V rms = 2.22 Vavg ,and for full wave rectifier , Vrms = 1.11 Vavg , since V max = V rms * sqrt(2)
OR I am WRONG ???
You are wrong bro
What you are saying is for the input signal. He is discussing about the rectified output.
You forgot the square root in denominator of Vrms...?
he was taking about half wave rectifier. Vrms/sqrt(2) is for a complete sine wave or a full wave rectification
thanks for the explanation, waiting for the ripple factor, i never did understand it from a book i hope you will make it clear.
are you going to talk about JFET in future videos?
can you recommande a good book with a good explanation in Electronics with the topics of Transistor and Amplifier.
another thing I am starting to study about Micro Architecture, do you have some PDF files that may help me, our you can recommande a book.
i know i Asked a lot but i saw all your video about digital Electronics and you helped me a lot by my exams and my understanding about the Topics.
Thanks a lot and Keep doing what you are doing.
Sir, isn't the average value of any waveform symmetrical with respect to the time axis supposed to be zero? I didn't understand why the average of square wave is Vm.
Please explain.
It's half wave rectified hence in the negative direction you have 0 voltage
This means when you take the mean you'd only consider the plus Vm
but still, shouldn't it be half ????
well..he made a mistake Vavg is Vm/2 and Vrms is Vm/sqrt(2) so..FF=sqrt(2)...#IITian
Average value of symmetrical wave about time axis is always zero. So we find the average value for positive half cycle only.
@@SurajKumar-zk2em you are absolutely correct #iiitian
Thank You Sir
Sir this is wrong for square wave , you said Vavg and Vrms are Vm but I'm getting Vm/2 and Vm/√2
That is for a sine wave. How are you getting it for a square wave?
@@blzKrg I believe he is right.
why Vavg and Vrms of square wave is same?
for rms and avg comparison, we can simply think of AM GM ineq.
Best sir...
thanks
Sir why we calculate rms value??
is it also called ripple factor ???
Sir why Vrms and Vavg of a square wave is Vm???

Tysm☺
oye avg of square wave is 0
He was talking about the rectified output of a square wave but he is wrong there too. Because for the rectified output of an input square wave, RMS voltage will be Vm/√2 and Avg voltage will be Vm/2. So, the form factor will be √2.
What is exactly form factor??
Can u explain how square wave have same RMS and Avg value? (time 3:15), thanks.
Think of it like a mean/average...
In a square wave the max voltage is always equal to Vm
Hence taking the mean of the same values simply gives you that value :))
7 months late lol
Jemima Khan thanks
well..he made a mistake Vavg is Vm/2 and Vrms is Vm/sqrt(2) so..FF=sqrt(2)...#IITian
