Okz my question is like this: A certain semiconductor has a max rated dissipation of 5W at 50 degree Celsius case Temperature and must be derated above 50 degree celisus case temperature \theta_{CA} = 5 degree C/W 1) Can the device be operated at 5W of dissipation without auxiliary cooling...

Well! for the 1st question, i don't have a schematic. i have written that as it came to me. It is just written that it is a single stage class A amplifier. So please be straight forward.

Hi audioguru! we do have a schematic, due to some problems, i cannot attach a schematic, but help u visualize that. It is a simple common emitter configuration class A amplifier. With R1 = 5.7 k , R2= 1K R1 and R2 forms a voltage divider bias. Vcc = 24V Rc= 330 ohms RE...

OKz here is the question to be considered: Determine the following values for the class A amplifier when operated with maximum possible output signal: 1)Min transistor power rating 2) AC output power 3) Efficiency 4) Maximum Load Power okz so here is what i think about these...

HI guys! well! i have got a question with me. Some forumlae i know and some i dont! please help me in solving it. There is a single stage class A amplifier which has Vcc =20V Vceq = 10V Icq = 600 mA RL = 16ohms Ip=300mA. We have to find: 1) DC Input Power 2) DC Power Loss in...

how to solve two equations involving complex variables?? Hi guys! well! i want to know how can u solve the following two equations simultaenously in order to find out Ix and Iy: (3+j4)Ix - j4Iy=10-------------(1) (2-j4)Ix +j2Iy=0---------------(2) please tell me the best methods to...

thanks a lot hallsofivy

thanks mr. data. what i have found is this that the only problem that i ws making was this that i was not taking n as a normal vector which should be first made a unit vector. when i make it a unit vector and make ds=dxdy/|n.k| i found the answer which is equal to 2\pi which I am also...

Hi guys! well! in the following question i need to verify The Stoke's Theorem: Q: Verify Stoke's theorem for F=6zi +(2x+y)j -xk where "S" is the upper half of the sphere x^2+y^2+z^2=1 bounded by a closed curve "C" x^2+y^2+z^2=1 at z=0 plane. Now here is the stoke's theorem...

okz okz! I am sorry for some mistakes. the correct answer of the above series is this that the series is DIVERGENT not convergent. it was my mistake! So that means that Status X was correct, we can compare it with 1/n and we can also compare it with 1/(n^1/2) both will give divergence as...

Thanks for ur Help StatusX! I applied Limit comparison test and it works with series 1/n as Bn. thanks a lot once again!

is the series covergent or divergent? I want to know that is the following series convergent or divergent?? \sum \frac{2}{\sqrt{n}+1} when i apply divergent test to it, it comes equal to 0 , it means that divergent test gets failed. then how to solve it? which test i should apply...

yeah that's true jpr0 thanks for ur help!

thanks for ur interest! there are no limits in this question the letter i is basically iota!

yeah berkeman is right here. You have to think in which area of electrical engineering you are interested most, and in which field of electrical engineering would u like to go in ur future. After deciding this, you can think about ur project relating with that field. If you are trying to ask us...
