Question

calculate resistance​

Answer 1

5 and 4 are in series

R = 5+4 = 9Ω

9Ω and 3Ω are in parallel

R' = 9(3)/12 = 9/4 Ω

8Ω and 9/4Ω are in series

R'' = 8+ 9/4 = 41/4 Ω

Answer 2

Okay..

So Rs=8 ohm

1/Rp= 1/3+1/(5+4)

=1/3+1/9

=3+1/9

=4/9

= 1/2.25

Thus Rp=2.25ohm

Thus total resistance = 8+2.25=10.25 ohm
