Lecture 1-4
Lecture 1-5 (Static) Electric Charge Electric charge is an intrinsic property of the fundamental particles that every atom is made of, and thus of any object in nature. Electric charge states: • negative (electrons, e.g.) • positive (protons, etc) • neutral (neutrons, etc) Obtaining net electric charges getting or losing charged particles For instance, friction can cause electrons to move from one object to another.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
