   ELECTRICAL FORMULAS 2.0

==============================

This is a better version of Eformulas for TI89 that I programmed before.  This version for TI92 Plus is a completely (graphics wise) awesome.  I have spent hours and hours on this one.  As I go along in class, I just update it and update it until I cannot update it enough.  As far as I am concern, my program is bug free.  I have done my best to satisfy my program users.  Although it is a big program, satisfaction is guaranteed. I hope youn will find my program very useful to you Electronic, AC/DC Fundamental geeks.

The first time you run "eformula.prgm" (Electrical Formulas 2.0), it will show you an agreement statement, it's nothing serious.  It's just for Windows 95/98 effect, so it would look like professional.  If do not agree  however, Electrical Formulas will not run, so please just press enter when you get there.  The demo is just a one-time program. If you agreed, the files for this program will be deleted, so don't worry about this.

Features:

  - Uses Ohm's law to calculate Amperes/Current, Resistance/Ohms, and Voltage/Volts
  - Uses Watts law to calculate Power, Voltage, Amperage
  - Uses the combination of Ohm's law and Watt's law for the other calculations
  - Can solve for Current, Voltage, Resistance in Series or Parallel Circuits
  - Has a built-in Resistor Converter to convert resistor color to values or values to colors        including the tolerance values (Minimum, Maximum)
  - Has an Electronic Term Database with 170 words with their respective meaning
  - Has a screen saver 
  - I think it has more than this but you have to check it yourself
  - I have used the power of TI's EXEC command to have a temporary shut off feature, pressing "S"
    Please , Do not, I say Do not change the EXEC command on this one,, I guarantee you that your     Calculator will crash!!!!!! You will lose everyhting!!!!! Seriously!!!

How to:

Run the Program---
 The main program is called Eformula.prgm, from the Var-Link screen look for this file on folder Eformula, or at the home screen type "eformula\eformula()"
 The program will modify your setting, Do not panic, it will go back to normal when you exit the prgm


MENUS:

   TOOLS--
    HElp= goto help 
    Glosarry of Terms= The database of Electronic terms
    Last Result= Will display the last result of the calculation for your own reference
    About the author=  He he he... of course about me

   SOLVE--
    This is where Ohm's Law and Watt's Law at work,,, you need two known numbers in order for the     prgm to calculate the good stuff. 
   
   PARALLEL--
    Solves for Current, Voltage and Resistance in Parallel

   SERIES--
    Solves for Current, Voltage and Resistance in Series

   RESISTOR
    Resistor stuff are in here.  This where you convert Colors or values and vice versa for the     Resistor
   
   EXIT-- 
    Self-explainatory, Exits the Prgm

I have also included some shortcuts for your convinience.  

On The Eformulas Main Screen: Pressing;
 P----will pause the prgm
 S----will shutdown the prgm,, it will not close the prgm, it will just turn off the screen to       save batteries
 C--- Will activate the calculator mode, so you dont have to close the prgm to make some       calculations, typing "close" there will go back to eformulas
 


It has some more features, discover it yourself.

If you have Ideas or Suggestions, do not hesitate to email me.  Or if you want to modify my program, just get a permission from me, I will probably accept it, if it will make my program better.

Please report any bugs to me, any comments are welcome.
