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
