Question

Can u pls solve this question thank u!! i having my physics paper tomorrow!!

Answer 1

13.875Ω & 5Ω

Step-by-step explanation:

in the first diagram:-

R = Rs + Rp + Rs'

Rp =>
`(1)/(7) + (1)/(1) = (1+7)/(7) = (8)/(7) \\`

Rp =
`(7)/(8)` = 0.875

4 + 0.875 + 9 = 13.875Ω

in the second diagram:-

R= Rp + Rs + Rp'

Rp => 1/6 + 1/3 = 1+2/6 = 3/6 => 2

Rp' => 1/3+1/3+1/3 = 3/3 => 1

R = 2 + 2 + 1 = 5 Ω
