Question

Find resistance between A and B​

Answer 1

Answer:

Current is not flowing because switch us not connected

Answer 2

Answer:

Here if you carefully look 3 is in parallel with 6 and that combination is in series with 8.

That whole thing is in parallel with 30.

So resistance between A and B is

R = ((3||6)+8)||30)

3||6 = (3*6)/3+6 = 2

2+8 = 10

(10||30) = (10*30)/10+30 = 7.5

R = 7.5 Ohms, is the resistance between A and B
