The solution will give you the total resistance for 2 or more resistors. R total r 1 r 2 r 1 r 2 so for two resistors in parallel the combined resistance is the product of the individual resistances divided by the sum of the resistances. The conductance is the inverse of resistance where g 1 r.
Resistors in parallel on the other hand result in an equivalent resistance that is always lower than every individual resistor.
