| Therefore, if we want to replace two parallel resistors with a single resistor, it needs to have a resistance that equal to the inverse sum of the individual resistors. This is an important conclusion because if you actually plug in numbers here you will find that the equivalent resistance is //less than// either of the two individual resistors. This means that **combining resistors in parallel will reduce the overall resistance**. Note that one has to be careful with using equivalent resistances for more complex circuits as the current that is computed is that through the equivalent resistor and //not necessarily// | Therefore, if we want to replace two parallel resistors with a single resistor, it needs to have a resistance that equal to the inverse sum of the individual resistors.
