Hello Sir! I am from Nepal. I am an Electrical & Electronics Engineering preparing for Master Entrance. I went through your lectures and your lecture was impressive but in this lecture i found error in ohm value as 40 ohm instead of 50 ohm. If we keep 50 ohm then the impedance (z) value is 22+j.20. Finally it's magnitude will be 29.732 with phase angle of 42.273 degree.

It’s rather 10+20j

sir try to adjust the sound output of the speakers its maximum on the left side kindly adjust accordingly

[@aryansinha9310]

sir 50 -40 kaise hua?

[@chhawinderpreetsingh8251]

please check weather u have calculated the zph in a right way as you may have calculated it by taking resistance as 40 but the resistance is 50

[@RaviYadav-is5zx]

sir since impedence angle is positive it means current will be leading the voltage so it should be capacitive one instead of inductive that u explained in the video

[@lvuskb7242]

A very warm thank you sir for your kind support to Student's...just like us....😊😊👌👌

LVU SKB please tell me how to calculate this Complex in FX 991 MS

[@askariwaqar]

The great teaching mathod.May ALLAH give you long life.

[@souravkundu4903]

in the formula of Power drawn. From where did you get that 3 ???

[@CinghAnkit]

its because taking the all three parts of delta connection the total power will be 3 times the power in single part.

[@AryanKumar-ji6mb]

bcoz it's a 3phase circuit

[@Designdgirl]

I thought it was meant to be √3 instead of 3 🤔 please someone explain

[@lyricalbrain2743]

@@Designdgirl for line quantity it is √3 but for phase it's 3

[@shahirabdullah5438]

thank you very much

[@yannickschmied302]

I got Zph as the impedance in the R || Xc (parallel part) . However when I add ZL, I get the the wrong number

[@suryasapkota4043]

he have 50 in one step and the very next step u have used 40

[@aamirdar5102]

How do we find the angle... U directly wrote the angle... Write the formula how to find angle

[@arunkumargd5524]

aamir dar yes..i also have the same doubt, if u know that..can u explain to me pls..

[@that_pahadi_chic9519]

Sir I'm unable to perform calculation on calculator

[@Warmatrix101]

thanx a lot sir..

[@chandragupta5418]

rishabh chauhan please tell me how to calculate Complex in FX 991 MS

[@Warmatrix101]

Bhaskaran M u have to put the calci in complex mode press shift then mode then select cmplx then u can use the' i' symbol for writing and calculating complex numbers

[@chandragupta5418]

rishabh chauhan plz show me j40+ 50*(-j25)/(50-j25) how to do in fx 991 ms.

[@saadmahera3520]

How to find j in calsi

[@sharankumar5402]

Ur answer for impedance is wrong and u have 50 in one step and the very next step u have used 40 how it make sense #omale

[@deathwitch1000]

he has calculated the problem using 50.

USING YOUR OWN HANDS ;)

[@chandragupta5418]

plz any one tell me how to calculate this complex form i fx 991 ms

[@amitanandanojha3419]

dont need any complex it is calculated as feneral calculation

[@maheshvhatkar9093]

Nicely explained

[@chandragupta5418]

mahesh Vhatkar please tell me how to calculate Complex in FX 991 MS

[@harshaa.b9103]

while finding Iph why do u only take the magnitude

[@sohankuasha]

Thanks sir

wow

[@amitanandanojha3419]

sir u have done mistake it is 800/2*pie

[@kl5317]

No, look at data it is given in rad/sec so it w which is given in question.
