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 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...
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 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...
