Dear all, I would like to ask you one basic thing. I know exactly how resitor works on electrical base. But I want to know if I know good how it works on physical base. This is my knowledge from primary school (for basic circuit). Input current and output current in circuit is still equal. This current depends on resistor parameters. But I am confusing by this problem: How can resistor influence current size in way, that this current is same on input and aslo output. Because if current is decreasing by conversion of energy to another energy, than this current should be different on input to resistor and output of it. Thank you very much.
