A power supply unit needs to regulate its output voltage. Write a function to calculate the required resistor value for voltage regulation given the desired output voltage and the reference voltage.

Formula

required resistor value $/$ reference resistor $-1$

Requirements

Function will pass two arguments

Use float data type for all values
