I'm confused between current and voltage sources; I get the text book definition but I am not able to understand real world difference. To me both current and voltage sources seem as the same. I understand that ideal sources doesn't exist. What is an example of practical current source? In order to produce current, we need voltage, so then isn't a current source also a voltage source? Since a battery is a voltage source and it produces current when connected to a circuit, isn't it also a current source?
Please help me understand real world example and usage of current source and how it is different from a voltage source.
