Question

the resistance if connected in parallel gives resultant value of 2 ohm and when connected in series the value becomes 9 ohm the valances of each resistance are
a. 3ohm, 6ohm
b. 4ohm, 5ohm
c. 2ohm, 7ohm
d. 1ohm, 8ohm

Answer 1

option a) 3ohm ,6ohm is correct.
1/Rp=
1/3+1/6=3/6
Rp=6/3=2ohm

Rs=6ohm+3ohm
     =9ohm
so both the conditions are satisfied
