Sometimes it is useful to make the analogy with water circuits. In this analogy resistors are like pipes, the higher the resistance the thinner the pipe (so that it offers more resistance to the flow of water). Voltage is like pressure and a battery is a pump. Putting 3 pipes in parallel makes...

I really don't know! I think I do not have a favorite topic. I like a lot Quantum Mechanics and Electromagnetism as theories, but I like many applications of physics to abstract and concrete problems. I dislike when there is too much math to obfuscate the physics, so I do not like mathematical...

I would like to greet everybody here and thank you for the fantastic forum! I've been using it many times in the past but now I want to contribute! I'm a undergraduate student (not for long I hope!) at the University of Trento.
