Find the equivalent resistance between point A and B

Answer

7.6 Omega`

Explanation

Equivalent current

Equivalent resistance between point A and B is
` = (3 xx 6) /(3+ 6) + 8 = 10 Omega`
Now `10 Omega` and `20 Omega` resistance are in parallel. The equivalent resistance point A and B is
`= (10 xx 30)/(10 + 30) = 7.5 Omega`
