An atom is composed of a nucleus and a surrounding cloud of electrons. Electrons are negatively charged. The nucleus has positively charged protons and neutral (uncharged) neutrons. The SI
unit of charge is the Coulomb (C). Charge of a proton = +e = 1.6 x 10^-19 C. Charge of an electron = -e.
Like charges repel and unlike charges attract.
A conductor has many charge carriers that are free to move. Insulators do not have mobile charges.
It is possible to charge an object by contact or by induction.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
