Electric Charges and Fields Class 12 NEET

  Electric Charges and Fields Class 12 Notes Chapter 1 1. Electric Charge  Charge is the property associated with matter due to which it produces and experiences electric and magnetic effect. 2. Conductors and Insulators  Those substances which readily allow the passage of electricity through them are called conductors, e.g. metals, the earth and those substances which offer high resistance to the passage of electricity are called insulators, e.g. plastic rod and nylon. 3. Transference of electrons  is the cause of frictional electricity. 4. Additivity of Charges  Charges are scalars and they add up like real numbers. It means if a system consists of n charges q 1 , q 2 , q 3  , … ,q n , then total charge of the system will be q 1  +q 2  + … +q n . 5. Conservation of Charge  The total charge of an isolated system is always conserved, i.e. initial and final charge of the system will be same. 6. Quantisation of Charge  Charge exists in dis...
