Chapter 19 Electric Charge and Electric Field 2. Law of conservation of electric charge(p457) The net amount of electric charge produced in any process Is zero. 3. The sI unit of charge is the Coulomb. (p461) The si unit of charge is the coulomb(c). 4. Electric charge is quantized(p461) g=nel, where n is a positive or negative integer, and e is a constant of nature called the elementary charge(基本电荷).1|l=1.60×1019C 物体带电量都是基本电荷的整数倍。电荷的这种特 性叫电荷的量子性( quantized)。Chapter 19 Electric Charge and Electric Field The net amount of electric charge produced in any process is zero. 3.
