Answer 2

From the above attachment you can see that ➡

• 3Ω , 3Ω , 3Ω are in parallel combination
• 6Ω is in series combination

Final answer ★

Let the equivalent resistance be - R

Parallel combination ➡

1/R' = ( 1/3 + 1/3 + 1/3 ) Ω

➡ 1/R' = 3/3 Ω

➡ 1/R' = 1/1 Ω

R' = 1Ω

Series combination ➡

R = ( R' + 6 ) Ω

➡ R = 1Ω + 6Ω

R = 7Ω

☆ In parallel combination we should always calculate the reciprocal of that no.

Suppose if 2Ω and 2Ω are in parallel combination then we should calculate it's equivalent resistance by,

1/R = ( 1/2 + 1/2 ) Ω

1/R = 2/2 Ω

➡ R = 1 Ω

If the values are supposed 2/3Ω and 2/3Ω then it will be,

1/R = ( 3/2 + 3/2 ) Ω

➡ 1/R = 6/2 Ω

➡ R = 1/3 Ω

☆ In series combination we should simply add the values.
