ELECTRICITY 1) Charge is a fundamental particle in an account in an atom.It may be positive or negative. 2) Like charges repel each other. 3) Unlike charges attract each other.       Coulomb(C ) :S.I.unit of charge      1 Coulomb = Charge present an approx.6*10 to the power of 18 electrons 4) Charge on 1 electron = Negative charge of 1.6*10 per C                                                      Q = ne Where     Q = Charge(total)                 n = No. of electrons                 e = Charge on one electron Current(I):   the rate of flow of charge is called current.                               ...
