hi, This is an old thread.. So if u'd like me to post it elsewhere, do let me know.. I need to calculate the theta using inverse-tan. But since micro-controllers do not provide much computational freedom, I was looking to solve it as the integral of 1/(1+x^2). Other than the fact that, integral...

yeah sure, let me know the answer as I have already posted my answer in the 4th post... Just wanted to concur with what was required...

Well, have u seen this? http://www.instructables.com/id/Pair-of-Hearts-Homopolar-Motor/ well give the sentiment a miss, but the idea is enthralling to say the least...

include a 10ohm 2Wpower resister or as you say a 1/2 watt 50 ohm resistor in series. this will limit the current to about .5 or .1A. but also the voltage on the coil will be affected. You should be able to measure the voltage of the battery while it is the ckt, same as the coil voltage, it will...

@ that time what voltage do you get at the battery source, if even that is like say, 1V. then it means that the current requirement of the ckt causes the voltage to drop. What is the current value recommended for the ckt, if the recommended value is less then u can try putting a small value...

Hi, but can you please share ur answer, if not the steps u used... Coz actually don't need to use the P=VI equation. I understand that the thread is over, but just wanted to know what the book expected you to do...

Hi, sorry Yungman, was entangled with my wrk the last few days. And well yes I did go through the :) long post, actually was not that long. I thought the toroid is to protect the ckt from noises (EMI, ESD, Switching noises) from the power distribution side and also to protect the other devices...

Hi, sorry couldn't get back to you... was entangled with work the last 10 days... will get back to you this evening(another 10 hrs...)

But Yungman, the ckt I posted in the DC part is a pure DC ckt, with battery source. So is it still a problem?

I know, but I will try to make him understand that, may be the way ssana has put it. That may do the trick.

No in the DB case the two currents are not cancelled. The current I[AB] is determined by V[DF] = 6V, and the effective resistance of ckt A. The current I[BC] is determined by V[ED] = 12V, and the effective resistance of ckt B. And then the current I[DB] is determined by the fact that the...

Hi yungman, this is with reference to the DC ckt I was asking about. Well actually, by the time I finished drawing the ckt, my doubts were cleared... actually no doubts, just laziness that led to a few assumptions. I love DC, one can eventually resolve the ckt without too much fuss...

No no... there is a separate condition.. I shall post the image soon, it will be more clear if we discuss on that once I post the pic, as I have specific questions on that.

I have a question folks.. Even a random number becomes finite once we have generated it. though the possibility of what the number will be is infinite, the number by itself is finite as the bounds are finite. Even in case of an ADC read of an AC analogous value, independently changing with time...

I don't have questions per say, only how to help someone else understand without embarrassing them, hope you understand. Well ssana I shall try puting your point of view ahead... And well yungman, I agree with you.. and well I guess as the implementation is only of case A type, there are no...
