This is a very trivial question in my opinion, but I was thinking about what a battery would be classified as. In the physics world, batteries are often used to represent a voltage source.
I feel like that a battery should be considered a dependent voltage source since a batteries voltage is dependent on the amount of current the load draws within a certain amount of time. An ideal battery wouldn't have this issue. But to me, batteries aren't independent sources like power supplies, which will always supply a fixed voltage (as long as it is CV mode).
The question is do you think batteries are independent voltage sources or dependent voltage sources?
