I am a college student, and I am learning the capacitor. Actually, I didn't focus on what my teacher said in class, because I think my teacher is not handsome, you know, girls always like handsome men, so in class I didn't get the knowledge of the capacitor. But my final exam is coming, so I have to learn it and I have no choice. So here my question is what the working principles and functions of the capacitors are. If you have some good passages about capacitors, or some good websites, could you please share them to me? I really really need to pass my final exam, otherwise my mother will not support my trip to Tibet with my roommates, so guys please help me. Thanks in advance for your help.
