a) 5 Ω
b) 9 Ω
c) 11 Ω
d) 13 Ωh
EXPLAIN IT PROPERLY ​

Answer 1

Answer:

◦•●◉✿Equivalent circuit of the above figure is shown which represents a special type of unbalanced wheat stone bridge.

If

Q

P

=

R

S

=n,

then equivalent resistance between A and B

R

eq

=

n+3

3n+1

r

From figure, n=2

⟹ R

=

2+3

3(2)+1
