What possible values of resultant resistance one can get by combining two resistances, one of value 2 ohm and the other 6 ohm?

Here, R1=2 ohm, R2=6 ohm

When the resistors are arranged in parallel combination we get,



Again, when the resistors are arranged in series combination we get


R = R1 + R2 = 2 + 6 = 8ohm
