Electric charge, Electric field, and Electric Dipole
Fast Track Revision Electric charge is the property of substance that makes it possible for them to exact electric force or to respond to electric field. Charges scalar quantity and its SI unit is Coulomb . There are some basic properties of electric charge. (i) Conservation of charge: The total charge of an isolated system is always conserved initial and final charge of the system will be same. (ii) Quantization of charge: the charge on a body is always integral multiple of basic unit of charge .i.e. charge on an electron (e). This phenomena is called quantization of charge. Magnitude of charge on a charged object q=±ne. Here, n=number of electrons and e=charge on one electron. q=±1e,±2e,±3e,............ Conductor and insulator: conductors are the material through which electric charge can flow easily . Insulator are the material through which elec...
