SIR ONE QUESTION Of A.C A.C mains of 200 volts & 50 hz is joined to a circuit containing an inductance of 100mH & resistance of 200ohm in series. Calculate the power consume ?
@@lecturesbywalterlewin.they9259 Carl Hansen made an impressive contribution wrt this problem on "geogebra". It is very interesting. It depicts the E-field and Voltage between the two rings and you can manually tune it with sliders.
Thanks Eugen and dr Lewin! I was just wondering, since I got 8 likes for my solution, that perhaps it could be a warning that I had made some mistake 😄. Best regards, /Ulf
Dear Professor Walter , have a good day , please could you kindly solve one numerical problem regarding lightening bolt striking a broadcasting mast , to indicate the effect of radius of blunt end of a lightening rod , thanks and best regards .
Sir , do you know H.C verma , i think he is your classmate 😄
I litreally Love yourphysics exper.. Videos Lot much , And i fall into Love in Physics Because of You!!!
Sir biggest Fan sir
Sir , what book would you refer to me for physics 🙂, as i am preparing for neet exam
ask your teachers
Sir, can you travel time? Is it practically possible?Can you travel at the speed of light?
use google
SIR ONE QUESTION Of A.C
A.C mains of 200 volts & 50 hz is joined to a circuit containing an inductance of 100mH & resistance of 200ohm in series. Calculate the power consume ?
piece of cake - *watch my 8.02 lectures*
Okey sir
only one component is consuming power in your circuit. think about that
I would add that last time I checked the answers Ulf Haller’s solution was also correct!
my apologies to Ulf!!!

I did the same in Desmos, but only for the E-field.

I do not solve problems for viewers - that too time consuming
Ok , Thanks a lot Professor Walter @@lecturesbywalterlewin.they9259
sir btw for future qns .........and answers can i mail u?
sure my email address is εΘσ/ς@lewin.com
I like you
Respected sir.
A student from India this side.
I am very much interested in astronomy. But not in engineering. What should I do?
Get aq PhD in Astronomy/astrophysics
Sir I am a biggest fan of your..❤Like my comment for all biggest fan...👍🏻
I'm a 8th standard student...but please let me know what is De broglie Hypothesis???
don't waste my time - use google
I am too here
Did you understand those equation
Out of my reach. By far .....
🙇😁🏆
Hi sir😊
I have a nice picture of Krishna on my wall - it was given to me by a friend in India when I gave 8 lectures in 2014
I thought I got the answer, now have to check for typos.
I remembr having read your solution and I sent it to Eugen and to Keith. I recall that they both agreed that it was not correct
I looked very quickly on your answer and I think you have a typo.
I see -(Q/k), but it should be -(Q*k).
Thank you!@@ulfhaller6818
@@ulfhaller6818 I do remember one solution had that mistake.
@@ulfhaller6818 Thanks much!
Can I be with you

Honestly the comments are so dumb💀. Y'all are asking professor such silly questions?
