hi. can u help me jst once..i can figure out the current for the first question which is 8 i think but im not sure how to calculate the urrent on the 12 ohms...i also know how to calculate the last question which is P=IV or P=I^2R or P=V^2/R please jst help me with second questionYour thread has been moved to the Homework Help section, where it is more appropriate.
The Homework Help section asks that you post up the work you have done so far, so we can see it and find where you went wrong, or suggest better approaches. We will not do all your work for you.
If you are in doubt about how to structure your post and what to include please read this thread: http://forum.allaboutcircuits.com/showthread.php?t=3002
so the current on the 10 ohms would be 3 and on the 6 it will be 5 right? on the first segmentYou could use the current division rule (Google it), otherwise you know the total current, the current in the 10ohms is obvious, the remainder goes into the 6ohms AB.
You then have X amps flowing into a parallel combination of two resistors...
It might help to re-draw it.
so the current on the 10 ohms would be 3 and on the 6 it will be 5 right? on the first segment
then i used I=(12/6+12)*5 to get 3.33 for the other 6 ohms so that means that 12 ohms is 1.67 ohms is this wrong or right?.. if not can u correct please
