Series/Parallel ResistorsWhen you do not have an exact resistor value in building a circuit, you need to combine two resistors either in series or in parallel. This app is used to find out all the combinations of these resistors making a desired resistance.This app is suitable for hobbyist or electronic engineers. Features:1. Calculate resistance of 2 resistors in series / parallel (equivalent resistance)2. To find out combinations of 2 resistors in series / in parallel making a desired resista
