This program might be useful to a student studying transistors, but it may be a little cumbersome to use. After all, the program needs to be restarted for every circuit. How would you alter the program so that it would ask whether or not the user wanted to try another circuit? In other words, the user could start the program and run it continually for 100 circuits if they so wished.
Perhaps more interestingly, what would be required so that the program could be used for homework generation? That is, the program would create appropriate circuits using new component values each time, and inform the user. It would then ask user to calculate the current and voltage by hand and enter them. The program would then determine if the user’s answers were correct (within a certain percentage to compensate for round off error). Another possibility would be to present the user with a multiple choice list of possible answers instead of having them enter precise values.
Lastly, how might you attempt to “draw” the circuits so that the components are visually identified?
