## Homework Statement

1 for picture38... apply loop analysis to find the current through the 2 ohm resistor

2 for picture39... apply loop analysis to find the voltage across the 10 ohm resistor

## Homework Equations

v=ir

kvl

## The Attempt at a Solution

i'm using a, b, c etc as current labels as well as loop names

1)loop a

4a+4(a-b)+4(a-c)=0

condenses to 3a-2b=0

supermesh c&b

-10+8(c-a)+4(b-a)+2b=0

using 2=c-b

condenses to 7b-6a=-3

i get b=1/3... which is so not right...

so wat am i doing wrong??

2)

loop a

4a+75+a+10(a-b)=0

2=c-b

supermesh c&b

-25+2c+10(b-a)+3c=0

wat am i doing wrong again?

i guess supermesh is my problem... or maybe the algebra... but i don't get it... at all.. got an exam tomorrow... so please help quick

thankyou
