Question

bhai mera ans 4 ohm hai ​

Answer 1

Answer:

1 ohm

Explanation:

I am attaching the pic .

Likewise, other two will measure 1 ,

Next picture will be like this :

l----------2-----------l

----------- ------------------

l----------2-----------l

So net wil be = 2*2/(2+2) = 1

Answer 2

Answer:

the equivalent resistance is 8 ohm

Explanation:

e.v = R1,R2,R3,R4 & V1,V2,V3,V4 resp.by ohm's law

therefore V = V1+V2+V3+V4..........(1)

put the eq (1) .....

V = R1×I +R2×I +R3×I +R4×I

V = I { R1+R2+R3+R4 }

V/I = { R1+R2+R3+R4}.........(2)

therefore V/I = R ............(3)

from eq (2) & (3)

R = R1 +R2+R3+R4

R = 2+2+2+2 , = 8 ohm
