Answer:

follow me for more grattitude

Explanation:

if you want the resistance as 4ohm

the connect two resistor in series and one resistor as parallel to that

fig 6 ohm 6ohm

l-•-------------^^^^^^-------^^^^^^-------------

l 6ohm

l----------------^^^^^^^^^^^^-----------------------

from above diagram

resistivity of series is

R1 +R2=6ohm+6ohm= 12ohm

and if we want 9 ohm then

we know that 1/R1+1/R2=1/R(FOR RESISTIVITY in parallel)

1/6+1/12

=1/4 = 1/R

R=4
