By applying the Ohm's law to the problem, the other resistance is 6.5 ohm

What is Ohm's law?

Ohm's law states that; the voltage is directly proportional to the current. Using the idea of Ohm's law; V = IR

R = V/I = 13 V/3 A = 4.33 ohm

This is now the effective resistance thus;

1/13 + 1/R = 1/4.33

1/R  =  1/4.33 - 1/13

R = 6.5 ohm
