Determine Vout

Determine Vout

Determine Vout

(OP)
I have, what I'm sure is a very simple circuit, and I need to determine Vout from the design attached. I'm sure I have to do superposition and use a potential divider, but I can't seem to get the answer given. Anyone that can push me in the right direction?

Cheers

RE: Determine Vout

Looks like howework from here... Not allowed on these forums

RE: Determine Vout

(OP)
Nope, example question in course notes, with the answer given, just not sure how they got there.

Answer is 14.23V.

RE: Determine Vout

Would have fooled me - an old strucutral! Only took one EE coursde - BECUASE I HAD TOO!!

RE: Determine Vout

It's a voltage divider output, resulting in 14.2308. Perhaps, you can show your work and someone can show you where your error is.

RE: Determine Vout

R1: ignore
R2, R3, R4: combine to one resistor
R5, R6: combine to one resistor

That's it, now you have your voltage divider.

Benta.

RE: Determine Vout

Maybe I'm being picky, but you can't get four significant digits on the answer when the resistors all have one significant digit.

RE: Determine Vout

"...significant digits..."

Well done.

RE: Determine Vout

hint: where is Vout referenced to?

Actually real answer is lots MORE significant digits if one were really really picky, like 14.23076923077......

RE: Determine Vout

This is definitely homework!

The exact answer is 185/13 ;)

RE: Determine Vout

Got ot laugh......My wife got a calculator at a garage sale for 50 cents. A week later she says it gives funny numbers. Every calculation comes out as a fraction. Trying the clear functions listed on the back did nothing. Just when you think that you are smarter than a fifth grader. Just what is that function and why is it needed? I'll try removing the battery next May when we return to the camp.

RE: Determine Vout

There should be a key sequence that sets the calculator back to decimal mode. which brand is it?

And yeah, homework is not allowed, as a general rule.
