<h3><u>Answer</u> :</h3>

First of all see the attachment for better understanding. :D

<u>Eq. resistance between C and D</u> :

➝ 1/Rp = 1/6 + 1/6

➝ 1/Rp = 2/6

➝ <u>Rp = 3Ω</u>

<u>E</u><u>q. resistance of upper part </u>:

(All three are in series)

➝ Rs = 3 + 3 + 3

➝ <u>Rs = </u><u>9</u><u>Ω</u>

<u>Eq. resistance of lower part</u> :

(Both are in series)

➝ Rs' = 3 + 3

➝ <u>Rs' = 6Ω</u>

<u>Eq. resistance between A and B </u>:

(Rs and Rs' are in parallel)

➝ 1/Req = 1/Rs + 1/Rs'

➝ 1/Req = 1/9 + 1/6

➝ 1/Req = (2 + 3)/18

➝ Req = 18/5

<h3>➝ <u>Req = </u><u>3</u><u>.</u><u>6</u><u>Ω</u></h3>

Answer:

Explanation:

Eq. resistance between C and D :

➝ Rp = 3Ω

Eq. resistance of upper part :

➝ Rs = 9Ω

Eq. resistance of lower part :

➝ Rs' = 6Ω

Eq. resistance between A and B :

➝ Req = 18/5

➝ Req = 3.6Ω
