Given a % error tolerance, optimised solution for an equivalent resistance is provided using 2 or 3 series or parallel resistors. Recommend using only 2 resistor combinations, answer arises in <0.4 seconds. Three resistors resistor combination solutions take approximately 7 minutes, and it is advised these solutions are for emergency use only. Full instructions available with example code by entering 'help resist'.
