1. The total equivalent resistance for resistors connected in parallel is given by the following equation. RT1=R11+R21+R31+.Rn1 Where: RT= total equivalent resistance n= number of resistors The file resistors.txt has the values of 6 resistors. Read the resistance values: (a) Calculate total equivalent resistance if resistors are connected in parallel. Ouput to screen. Set precision to a tenth of an ohm. Output format: The total equivalent resistance is (ohms) if resistors are connected in parallel. (b) Calculate total equivalent resistance if resistors are connected in series (sum). Output to file. Output format: The total equivalent resistance is (ohms) if resistors are connected in series
