As we have learnt 

 

Sign Convention - - wherein

Applying kirchoffs voltage law 

-1*i+10-4-2*i-3i=0\Rightarrow i= 1 A(a..to..b ..via ..e)

Current = V/R = (10-4)/6=1 ampere 

 


Option 1)

\frac{7}{}3 A from a to b through e

Option 2)

\frac{7}{}3 A from b to a through e

Option 3)

1A from b to a through e

Option 4)

1A from a to b through e
