Ohms Law Calculations

VERSION 1.1

This program takes the 12 basic Ohm's Law expressions and
allows you to calculate Watts, Ohms, Volts, and Amperes with
any 2 known values.

You may enter a number of up to 6 digits. The output will be
calculated to the nearest 1/100TH.

The expressions used to calculate are as follows:

TO OBTAIN WATTS:

1. (E SQUARED), DIVIDED BY R;

2. (I SQUARED), MULT BY R;

3. E MULT BY I;

TO OBTAIN OHMS:

4. (E SQUARED), DIVIDED BY W;

5. W, DIVIDED BY (I SQUARED);

6. E, DIVIDED BY I;

TO OBTAIN VOLTS:

7. I MULT BY R;

8. W DIVIDED BY I;

9. SQUARE ROOT OF (W, MULT BY R);

TO OBTAIN AMPS:

10. E, DIVIDED BY R;

11. SQUARE ROOT OF (W, DIVIDED BY R);

12. W, DIVIDED BY E;

WHERE E = VOLTS; I = AMPS; R = OHMS; W = WATTS.

The Program is completley menu driven, additional
documentation should not be necessary.

To give you a example, start the program at the DOS prompt by
typing "Ohms" and press the Enter key. A brief version and
description screen will be displayed.

Let's say you want to know how many Amps an electric heater
draws. You know how many Watts it consumes, as well as the
operating voltage.

At the MAIN MENU, press "4", and at the SUB-MENU press "3",
to calculate Amps when the Watts and Volts are known.

Enter the value for Watts. For our example, lets say 1200
Watts. Next enter the value for Volts. Let us assume 120
Volts.

The program will take the correct expression and calculate
the Amps. For this example, the expression = W, Div by E.
1200 Watts, Divided by 120 Volts = 10.00 Amps.

You may calculate another similar value, return to the sub-
value, or quit the program.

Please notice the result is for DC or AC resistive circuits.
Also for AC circuits, the results are for single phase
circuits.

You are free to copy and distribute the program as long as
you do so by copying the program and documentation together
without alteration, and without charge. If you find the
program useful, a contribution would be appreciated.

The author assumes no responsibility for inaccuracies
obtained from using the for-mentioned program.

Please report any problems to the author.
