700024 Lecture Notes - Ampere, Electric Current
Document Summary
As learnt in higher school certificate, charges originate form protons, neutrons and electrons. As we also learnt a while back, opposite charges attract each other, which cause an electric charge with the introduction of current and voltage within the circuit or the situation. An object is charges if it is able to attract to small pieces nearby such as paper or cork. Charge is an electrical property of the atomic particles of which matter consists, measured in coulombs . The charge e on one electron is negative and equal in magnitude to 1. 602 * 10^-19 c, which is called as electronic charge. The charges that occur in nature are integral multiples of the electronic charge. Combing dry hair can cause it to crackle and the strands of the hair to stand on end, the comb after that can also attract paper. You give someone an electric shock while shuffling along a synthetic carpet and touching them.
