SUMMARY
When two resistors, denoted as $$s$$ and $$t$$, are connected in parallel, their combined resistance $$R$$ is calculated using the formula $$\frac{1}{R} = \frac{1}{s} + \frac{1}{t}$$. To determine the change in resistance when $$s$$ is increased by 1 unit and $$t$$ is decreased by 1 unit, first compute the initial resistance $$R_i$$ and then the final resistance $$R_f$$. The change in resistance is given by the equation $$\Delta R = R_f - R_i$$, which provides a clear method for evaluating the impact of the changes in resistor values.
