for question 2Hi Cf,
Welcome to AAC.
Could you please post your effort in solving the assignment, we can advise of any errors.
Yeah... whoever wrote question 5 is an idiot.QUESTION 5 I am completely confused
We need to see your work -- all of it -- otherwise you are forcing use to pull out a crystal ball and try to figure out what you are doing, or think that you are doing.for question 2
I=6 and 2/7
=176*6 and 2/7
=1106 and 2/7
power in 24 ohm
=1290 and 2/3
And we are NOT mind readers -- we have little chance of guessing why you stuck unless you show us your best attempt as far as you are able to get it so that we can see what you were trying to do and where you got stuck. Show your work!for question 1 I am stuck because of the Va-voltage controlled source
This is wrong. And since you won't show us your work, it's awfully hard to even guess where you might have gone wrong, so I won't even try. Show your work!question 3 i got Rth as 10R/17
You got some of them right, but at least one of them wrong. But since you only give answers, I would have to polish up that crystal ball and pull out by old mind-reading self-study course from years back to figure out where. But if you would have shown your work, I probably could have helped you find exactly where you went wrong. Show your work!QUESTION 4
What is causing the confusion? What parts seem contradictory? What information do you think is missing. Again -- we are NOT mind readers!QUESTION 5 I am completely confused
Thank You it makes sense to me now.Yeah... whoever wrote question 5 is an idiot.
I am going to guess that 15V is 15 Volts.
V across 2 Ohm resistor is the unknown that you need to find. My advice is to give it some other name.
I am guessing 5v at the dependent voltage source is actually 5*voltage across 2 Ohm resistor.
Step 1. Assign reference node. I would use the bottom of the circuit for the reference node.
Step 2. Simplify the circuit. You have 20 Ohm and 40 Ohm resistors in parallel, find their equivalent resistance and replace them with it.
Step 3. Do the nodal analysis.
Your last assertion seems somewhat ambiguous to me.Thank You it makes sense to me now.
I named it Vx
I got Vx as 5V
And power is supplied to the 15 volts, 30W
Sorry and thanks for bringing that up.Your last assertion seems somewhat ambiguous to me.
A simple change of one word can drastically change the meaning of a sentence. Consider:
And power is supplied to the 15 volts, 30W. This would seem to mean that power is flowing into (being absorbed by) the 15 volt source.
And power is supplied by the 15 volts, 30W. This would seem to mean that power is flowing out of (being supplied by) the 15 volt source.
Which do you think is true? Is power absorbed by or supplied by the 15 volt source?
