Military power, strength, and national security are the goals of a prince.
Machiavelli’s philosophy is basically to become a good leader you must do anything even it is immoral and wrong. He first writes that a prince’s duty concerning military matter must always think of war only, even in times of peace. They must know their surroundings exactly so they can defend and make effective strategies to counter the enemy’s attack. They must also know historical battles so they will be able to learn their tactics and improve on it. He then talks about the prince’s path: should the prince be generous or a miser. He is saying that it is better to be known as a greedy prince than a generous prince because if the prince follows the good path it will only lead him to destruction while being greedy will result in his safety.
As someone who is taking an electrical theory course in college, your total resistances and total currents are definitely correct. Furthermore, your final statement is correct (given that your lightbulb currents are correct).
I'm not completely sure if your current in the lightbulbs are correct because I'm pretty "Brain-ed" out from the semester and electrical theory isn't my best subject. I'd double check with some friends on those two statements.
I think the trouble is that I'm having a hard time following your logic. Overall, it appears you do have logical reasoning. Hope I helped a bit!
