They would have done their B.Tech. from the IITs then. It has already been mentioned that if you want to do PhD in physics, B.Tech. will be of no use in securing admission to the grad schools
Does anyone else have knowledge regarding this subject? I am running out of time.
That post gave me a lot of info. But, if i want to do specialisation in physics, shouldn't i take up B.Sc. physics? And what about the Masters? Do you recommend doing that? Lastly, i live in India. So, what are the chances of a Canadian university accepting my B.Sc. degree and funding my Masters...
I want to be a theoretical physicist. I have great interest in astronomy and want to pursue the same. Because of lesser research opportunities in India, I want to move out to US in the future. I have just given my board exams. I intend to do my B.Sc. Physics Honours from India. I have read that...
I am not pursuing any degree as of now. iI am yet to start going to college
As i mentioned in the first post, my goal is to become a theoretical physicist. I have read on this forum that some students were able to get a PhD in physics right after doing their engineering. So, as the combined...
I want to be a theoretical physicist on astronomy and have just passed out of school. To achieve my dream, I should get a degree in a Physics course (like B.Sc. Physics Hon.), followed by a Masters and then apply for PhD. I have also read that some students got a PhD in physics after completing...
when a formula has been derived that power can be added in series then why can't we use it?
when will we use that formula or how do we use it in this question?
please throw some light on the above questions
Let me get this straight
To find the current FOR THE ENTIRE CIRCUIT
P = 40W +60W
P =100W
do you agree with that?
Then, do you agree that P= VI
100W = 220V*I FOR THE ENTIRE CIRCUIT
In the same way, in the question I mentioned above, why can't we directly find the current in the circuit and as the bulbs are connected in series, each will have the same current
Agree with whatever you said above
In the website I mentioned above they have used bulbs as an example to illustrate the concept. So, in that case if the bulbs are connected in series they won't get the rated voltage and hence they won't dissipate the maximum power
So knowing this fact why do...
It seems to me that u are right but still I would like to mention this website. It shows the resultant power as sum of all the other powers
Just click on next a few times and u will see it for yourself

oh sorry!
I forgot to mention the word "power" i.e. I meant to say that "the power in a series circuit is the sum of the powers of all the conductors connected in series"
consider this
the power in this case will be the powers of both the bulbs
P = 60W + 40W = 100W
Now, P= VI
100W =...
is the current correct?
i have read on an online source that the power in a series circuit is the sum of all the conductors connected in series
first reply to this
then i will reply furthur
A 60W,220V bulb and a 40W,220V bulb are connected in series to a supply of 220V. Find the resistance of each bulb and the current flowing through each bulb.
My Solution:
I took the current to be same as the bulbs are connected in series.
As the current will be the same in each bulb, I took...
