Your script should output the effective resistance of the circuit, in ohms. You may do so simply by omitting the semicolon from the line that calculates this value or if you are feeling creative, use an fprintf statement to display your effective resistance.

Step $5$: Run Your Program

In your MATLAB window, you will see the green "run" arrow in the upper middle to upper right of your window under the "view" tab. The first time you run your code you will need to save it$.$ Be sure to save it in your MATLAB folder, where you will want to save all of your MATLAB code. MATLAB will look in the MATLAB folder for all of your files.

$7$

When you save your program you need to give it a name WITHOUT SPACES. Unlike Word or Excel or other programs you are likely used to using, the name of a MATLAB script cannot have spaces.

When you run your code, if it works you will see your questions from the input statement pop up in the command window after the $>>.$ Click in the command window, and type in the values of the resistors from the test cases below. Press "Enter" or "Return" after typing each value.

Step $6$: Testing and observations

Test your program with the following inputs. Remember to press Enter or Return after each number.

$560,560-$ The result should be $280\mathrm{.}0$

$560,1000-$ The result should be about $358\mathrm{.}974$

$330$ and $1000-$ The result should be about $248\mathrm{.}12$: You will build this circuit tomorrow.

Some things to think about: What happens when you put a resistance of $0$ for one of the resistors? What if you give one of the resistors an infinite resistance $($by typing Inf as one of the inputs$)?$ What would a zero or infinite resistance mean in a circuit?
