I have a few questions about op amps, but I'm fairly new to the whole EE thing, so keep that in mind while answering. Thanks!
I am trying to use an op amp between a 6V solar panel and a 4.8v NiMh battery as a comparator. I want the solar panel to stop charging the battery when the battery voltage hits 5.6v. I'm using the comparator in a inverting circuit and I was wondering two things:
- Is there a voltage drop from +Vcc to Vout?
- If the panel outputs 200mA max, will the battery charge at the same current?
Also, I'm currently a ninth grader and I don't have any opportunities to learn about electronic engineering. I tried using the Internet as a tool for learning, but it hasn't gotten me very far. Is there any way that you would recommend going about learning the subject?
