Parallel resistance is simple to calculate once you know how to do it. This skill may help. To get the total resistance of two resistors in series, add the resistances together. Parallel resistance calculated by this skill is a little trickier. The formula is: Parallel Resistance = (R1 * R2) / (R1 + R2). You can use this skill to calculate parallel resistance for two resistors. I don't like dividing by zero so avoid resistors with a value of zero ohms.
