Unformatted text preview: There are two kinds of electric charge: positive and negative; the SI unit of electric charge is the coulomb (C). The magnitude of the charge on an electron or a proton is e = 1.6010-19 C. The electron carries a charge of - e , while the proton carries a charge of + e . The charge on any object, whether positive or negative, is quantized, in the sense that the charge consists of an integer number of protons or electrons. The law of conservation of electric charge states that the net electric charge of an isolated system remains constant during any process. An electrical conductor is a material, such as copper, that conducts electric charge readily. An electrical insulator is a material, such as rubber, that conducts electric charge poorly. Charging by contact is the process of giving one object a net electric charge by placing it in contact with an object that is already charged. Charging by induction is the process of giving an object a net electric charge without touching it to a charged object.charged object....
