u are really great ,Sir. u have reduced my burden to read books to a large extent. by watching ur lectures, i dont need any kind of other books or material to read.
U r explained the concepts in a very good manner.
I'm really so much thankful to u.
Sir in centre tap while calculating PIV u're like Vi=Vm.now calculating Vm separately? Is it different for bridge?how did u considered Vi as Vrms?
Actually I too got the same doubt
Calculate the current-commutation time (u) if Ls=10mH, Vs=240V, and Id=4A and f=50Hz.
Determine the value of Ls that leads to a current-commutation time of 20o.
If we say that the current-commutation time is 20owhere is the time in that and what is its value
bridge rectifier simplification: VDC = 0.9*Vrms(secondary), when ideal diode considered.
Thanks again: another great tutorial.
Very helpful. Thank you
How did you put Vi to Vrms??
Please upload problems corresponding to full wave and half wave rectifier
great sir carry on
Sir please Solve this nemarical.
A full wave bridge rectifier with an R
L load is connected to a 240 V source of the load resistence is 1200 ohm and L>R . Determine following.
1) Average load voltage.
2)Average load current.
3) RMS value of the load current.
4) Average current in each diode.
Thnx neso academy 👍
Plz sir make videos on multivibrators.
thanks for this numerical
awesome stuff
Please upload operational amplifier lectures
U can say about half and full wave rectifiers with filters
why we took vavg as DC voltage output??
How to do the same math if we use parctical diode 1N4007???
Please make rectifiers with filters also pleasee
If I have a transformer and the input is120 v. and output is and output is 197 from center tap no load. How would I figure all that out. To find the capacitance.
how VM=2vm/π? its Idc
Shouldn't Piv be constant?
sir (Vrms) is equivalent to( Vdc) so why you assumed (Vi) as( Vrms) , it should be (Vavg ) . ,????????
at 2:35 , how Vrms = Vi ??
Vrms is nothing but input ac voltage.therefore both are same
@@shaikvahida4787 Vrms is Vmax/2 and Vinput =Vmax sin(wt) ,how Vinput and Vrms are equal???
@@shaikvahida4787 no buddy its dc voltage .
As transformer converts ac to dc in secondary side it's dc voltage i,e 22v and RMS is equivalent to dc so RMS = 22v
@@reshmabegum2516 ab kya karunga iska 4 saal baad, graduate ho gaya ab toh😂
How's Vi=Vrms
The expression for Vrms is derived for load voltage/current
The 220V supply AC is in RMS value (by defaut any ac voltage is given in Rms). Hence the 22V is also in RMS.
But RMS is equivalent to dc value
best teacher in world
sir what is the output frequency for half wave rectifier
Arun Reddy (fmax.)
Sir, how did you conclude that vrms=vi?
Please do reply
Same question from this side as well
@@khushiagarwal8890 any explanation for that..?
220v supply volt is in rms value(any ac voltage is in rms value)...that why secondary voltage is in rms values..i hope you will get answer🙂
@@daryentanwir9091 average or mean value of pure ac component (that we are given as input) is zero...then how come the rms value (square root of mean of squares will exist )it should be zero right?
@@daryentanwir9091 are kehna kya chahte ho?
Please how did you get the PIV to be 31.11
Piv>31.11
Not equal to (piv>2Vm)
Sir as of my knowledge,
Frequency is a source dependant quantity, and if there is no change in source then frequency must remains same i. e 50Hz
And what u write over their in explanation is also corrt
. So how is it so sir
Pls explain
doesn't the efficiency always remain the same (81.05%) ????
No it also depends on Rf(= diode resistance) and Rl(= load resistance),here Rf=0 therefore it will always near 81%
Sir Can help me
what about 2Vm in C part
This is a full wave bridge rectifier so there will be vm only not 2Vm.
how is vrms=vi
The 220V supply AC is in RMS value (by defaut any ac voltage is given in Rms). Hence the 22V is also in RMS.
how can u get more questions of electronic
is this transform ratio will be constant ?
yes
constant , and given in question
This is a centered tapped full wave then why we take piv>=vm
In previous u derive it as piv>=2vm
this is not centre tapped rectifier this is the bridge-type rectifier
that is why piv>=vm is used here!
@@makshithsaai2821 ok thanks
sir why take Vrms =22v
RMS gives us average value of AC quantities. since, at the input we have AC as input.so, Vrms=Vi=22V.
if vrms gives us the avg value of voltage then why theres vavg ??
@@shivanshukhodeiitrVavg is for DC power supply....I think 🤔
Sir please explain briefly why T=2T'.
Look at the graph that sir drew. There you can clearly see that T=T'+T'=2T'
T' is the time period (completes a pattern) of the output signal. So for every input time period T we are getting two pulses (patterns) of output.
sir what will happen if the trnsform ratio is interchange
If transformer ratio gets changes than output voltage will get change accordingly PIV will change
zainab MUT post your question I will help you
How Vrms=Vi??????
at 4:21 you made a mistake
it is not vrms it is vac
how vi = vrms ??
In the qstn, The input voltage is Ac so, we take it as Vrms
how vm=2vm/π? its IDC=2im/π..
It is derived..
I think rms value is dc voltage
nope , dc value is average value
Thanks
please reply
How Vrms=Vm/√2 and Vavg=2Vm/π ?
I think there are some mistakes in this lecture.
May be you have missed the videos of full wave rectifier
you expressed this topic too superficial.
