    What exactly is electric field?

    Recently I am reading about electirc and electromagnet. I found electric field and the field line a bit confusing. What forms the field, or the field line? Is it photon? Secondly, why must electron orbit around proton, and not proton orbit the electron? :confused: Thanks in avanced.
