Please don't post unrelated questions to this group. It would be better for you to post this in a more appropriate group (like Physics) and then post a link to it in any of the chat windows if you find no one available to help out in that group. This helps keep the groups on topic. Please refer to our Code of Conduct if you require further clarification: http://openstudy.com/code-of-conduct

sorry @asnaseer

4. asnaseer

np - you probably weren't aware of this. :)

Yes From now I will post questions in respective group sorry again.

6. Brent0423

what do we need to solve for?

@asnaseer

@Brent0423 You have to solve for |dw:1339807722414:dw|

and total current

10. Brent0423

total voltage total current Resistance for resistor number 2

11. Brent0423

thats all?

12. experimentX

|dw:1339797020131:dw|

13. Brent0423

what do we know?

14. experimentX

can't copy my own picture ... something wrong this system code ...or my browser??

16. experimentX

What other factors do we know??

other factors we know are total resistance =82.5 and current in first branch is 20mA

18. experimentX

let, r1 + r2 = x http://www.wolframalpha.com/input/?i=1%2F82.5+%3D+1+%2Fx+%2B+1%2F330 so x = 110 ohms ( I presume)

19. experimentX

since the current remains same, the total voltage is IR = 20x110E-3 = 4.4 V

20. experimentX

Do you know R1 or R2 ??

21. experimentX

or voltage drop at one of the resistor?

R1=10 @experimentX

23. experimentX

R1 + R2 = 110 R2 = ?
