Question
product/sum formula for resistance in parallel works only for 2 resistors?
Solution
No, the product/sum formula for resistance in parallel does not only work for 2 resistors. It can be used for any number of resistors. However, the formula becomes more complex as the number of resistors increases. For two resistors, the formula is R = (R1*R2) / (R1+R2). For more than two resistors, you would need to use the formula 1/R = 1/R1 + 1/R2 + 1/R3 + ..., where R is the total resistance and R1, R2, R3, etc. are the resistances of the individual resistors.
