I have a system consisting of 4 identical components. The components are independent so that the probability of failure of each component is independent of the other.
I have a failure rate, lambda, of 4.60994 /10^6 hours.
I need to calculate the MTBF of the system assuming that 75% of the...
Thank you all for your help. They are all instructive in different ways. The calculus solutions are the ones that did it for me.I think that's what the authors were really looking for.
I am working through a problem in Edminister's Electric Circuits, 6th edition (I notice it has been recommended once or twice in a different forum).
The problem goes like this:
A capacitance of C farads has a current i = (Vm/R)e-(t/RC) (A). Show that the maximum stored energy is (1/2)CVm2.
I...
The attachment I have is a pdf file. From the content one of the forum messages it seems I cannot do this from the Quick Reply screen. Is there any other way I can do it?
I have scanned the relevant pages from the book. Unfortunately I cannot attach them. Apparently I need to be in the New Post page but I cannot fin the Post Reply button.
When I have sorted this out I will attach the file.
Hi BradtheRad
The vacuum tube is an interesting analogy and probably is similar to the original problem in that there are conductors in proximity to one another and the device relies heavily on electric fields (the grid is at a negative potential relative to the cathode to prevent, rather than...
I am reading Ralph Morrison's book Grounding and Shielding: Circuits and Interference, 5th ed. and in the section on electric field patterns he has a conductor, A, containing a charge (charge Q at potential V1) completely surrounded by a shield, so no electric field escapes. This screen is...
I am given the task of documenting some embedded C code written by a contractor who has since moved on and am having trouble understanding some scaling used in an expression for computing the PWM value required to maintain a given output voltage for a buck converter operating in discontinuous...
Hi Keith
Thanks for the response.
Yes - I was thinking on a similar line. So what he is really saying is that A0- is >> 1, rather than infinity, otherwise it causes complications with the maths. I can understand it from your viewpoint.
The other way I looked at it is to assume that as the...
Hello.
I am reading through the book Analog Circuit Techniques with Digital Interfacing, by T.H Wilmshurst, 2001, and have reached section 3.8, Common-mode response.
Here, he states for the ideal op-amp:
V0 = A0(Vi+ - Vi-)
and for the real op-amp:
V0 = A0+Vi+ + A0-Vi-
Then he applies this...
