This is a program that calculates resistance.
Enter 1 for parallel or 2 for series: How many resistors are there: 
Resistor 1: Resistor 2: Resistor 3: 
The total resistance is: 6.127336 Ohms

Would you like to calculate another(y/n): Enter 1 for parallel or 2 for series: How many resistors are there: 
Resistor 1: Resistor 2: Resistor 3: 
The total resistance is: 56.100002 Ohms
