PPT-Electrostatics

Ch 20 What is electrostatics The study of STATIC ELECTRICITY Static electricity is electrical charges that can be collected andor held in one place This is different from current electricity. 1 Electric and 64257elds 1 111 Electrostatic Force 1 112 Uniform electric 64257elds VITEEE Conductors. Prof. Hugo . Beauchemin. 1. Introduction. We have seen most of the powerful concepts needed to understand electrostatics. W. e now turn to concrete applications, solving the equations. we saw for various types of system encountered in experiments . r
