In this blog post we will create a Python program that will help us calculate the total resistance when two resistors are connected either in series or in parallel.

This program will be based on the following formulae:

#### Program Flowchart

#### Create the Code

Your task consists of implementing the code described in the above flowchart using Python. Then you will have to test your code by completing the test plan below.

#### Test Plan

Once your code is done, complete the following tests to check that your code is working as it should:

Test # | Input Values | Expected Output | Actual Output |

#1 | R1: 6 (Ohms) R2: 6 (Ohms) Series |
12 Ohms | |

#2 | R1: 6 (Ohms) R2: 6 (Ohms) Parallel |
3 Ohms | |

#3 | R1: 6 (Ohms) R2: 12 (Ohms) Series |
18 Ohms | |

#4 | R1: 6 (Ohms) R2: 12 (Ohms) Parallel |
4 Ohms | |

#5 | R1: 33000 (Ohms) R2: 56000 (Ohms) Series |
89000 Ohms | |

#6 | R1: 33000 (Ohms) R2: 56000 (Ohms) Parallel |
20764 Ohms |
