Exam Paper Question

[Suraj143]

I cannot solve this exam question please help me to solve this out.

For a Transistor below specifications are given.

Vcc = 5V
Vce(SAT) = 0.2V
Vbe(SAT) = 0.8V
Vbe(ACT) = 0.7V
b(Beta) = 50

Find

1)Ic
2)Ib
3)Vbe
4)Vce

Please post the circuit for viewing.

I agree, your data supplied is incomplete.
That's why rezer asked for the circuit.
There should be a base resistor value as well as collector resistor.
That's required for basic fixed biased bjt circuit.
To get Ic, you need Ib, to get Ib, you need Rb.

Get what I mean!

Also note that we don't mind helping you but we won't do all the work for you - at least make a reasonable effort.

Since the exam was 49 days ago, what was your answer? What was the correct answer?

I think this exam question was shown with a schematic on at least two other forums.
It was extremely simple.

i know how ur circuit looks like. u first need to check in which mode the transistor is operating. If it's operating at the Saturation mode(SAT), then Ic=(Vcc-Vce)/Rc, where Rc is the value of the resistance between Vcc and Vce. Pls show me the circuit and i'll solve it all.

 

[Hero999]

This is over three months old he passed or failed his exam ages ago so there's nothing we can do about it now.

Hi,

For the saturation specs all i could come up with as that Rb=43.75*Rc,
but without knowing anything else that's about it.
It looks like the OP flew the coupe anyway.

Presumably that would be an Air Coupe?

 

[MrAl]

Yeah i guess so

 

[Roff]

Yeah i guess so

Sorry, MrAl, I was messing with you and making fun of your spelling. I think you meant "coop".

hi
are it is serious discussion

Ron:
Yeah, i speeled that rong , he he
If you look at some of my posts you will almost always find at the bottom:
"Reason for editing: Spelling"
I have a habit of typing faster than i can spell

vinod:
Actually i was serious, as the original poster seemed to vanish and not
bother to come back to find the replies. Without further input from him/her
we cant proceed with this discussion, that's all i meant.
