Document Summary
Electrons transferred to another object leave _______ with same value of charge. By transfer of charge from one object to another. It"s used to remove particulate matter from combustion gases. It can be used to reduce air pollution and eliminates approximately 90% by mass of ash and dust from smoke. By tracking the rate and direction of movement of different sized charged oil drops, it established the value of charge on the electron e = 1. 60219x10-19 c. C = coulomb is si unit of charge. Conductors - metals (low t metal oxides supercond. ) Charged ebonite rod deposits negative charge (electrons) onto electroscope. Due to repulsion of like charge on the two legs. Objects become charged because negative charge transferred from one object to another. Series is a ranking of materials by order in which they tend to lose or gain electrons.
