So I have these huge doubts on the deep nature of the force we refer to as "electricity" or "electric current" in our daily lives. I want to know exactly what it is and most online resources are very circular (electricity is electric current which is electric fields which is electricity etc.) It's difficult to know what to ask first but let's devise a simple practical example for starters. When I plug my, say, electric fan to the outlet and turn it on, is it a bunch of free electrons that pour into its electric motor and power it? I think it's not, but then what is it? Is it an excitation of electrons that passes on as a wave (more like it)? Well I have many more questions but they'll only pop out when the dialogue is started! Thank you!
