I was going to ask if there was a way to have only up to four decimal places displayed.
However, I believe I found the issue(s). If you enter a value in the text box, say 240 volts and press enter, everything is fine. Take note that when you press enter you also change the resistance.
However if I enter a real small value for voltage, say 10 volts, then everthing goes funny. Such as the current displaying
1.980198E-02
then the voltages across the two resistors is wrong. I made the text boxes bigger so I could see the total number being generated. I would like to have only 3 or 4 numbers displayed.
The other item is that no matter what voltage you enter, if you click the resistor then it is using 120 V divided by the total resistance, not the value of voltage entered in the box. That is a function of Module 1.
