One unique way to solve electrical circuits is by using Thevenin's and

Norton's equivalents.  By starting at one end of the circuit, with a

single source and one element, one can add sources and elements, one at a

time, until the circuit is reduced to a single source and one impedance. 

This Group of programs will prompt the user for the first source and

element, then draw the circuit equivalent.  From there the user has the

choice of: 

 1.  Converting to the Thevenin's or Norton's equivalent circuit.

 2. Adding a source.

 3. Adding an element. 

 4. Finalizing. 

 5. Quitting. 

 6. Starting over. 



Option #1 draws the origional circuit, then draws the Thevenin's or

Norton's equivalent circuit next to it.  When option #2 or #3 is chosen,

The previous circuit is drawn, showing how the new element or source is

added.  Then the new equivalent circuit is drawn next to it.  Option #4

changes the drawing from impedance to real elements.



The Drawings that this program creates are quite nice and really

informative.



To run this program make sure all programs and functions are in the same 

folder.  Then simply enter ThevNor() on the equation line.



Included with this group is a function called DegAng.  Its purpose is to 

convert a complex number from rectangular coordinates to a magnitude and

an 

angle in degrees.  Even though the answer is returned in the form of a

string, 

this function has proven to be very handy for getting answers in the form

I 

want them in.

Ex.  DegAng(6+2i)

                               "6.325<18.43degrees"
