Charge conservation

  1. Sep 17, 2014 #1
    A isolated system in which number of charges present is always constant. Suppose a high energy gamma radiation enters in to the isolated system and produces positron and electron (pair production), now the total number of charges present in the system increases right? Then how the charge conservation is true?

    The total charge is conserved, not the total number of charged particles. An electron carries a -1 charge. A positron carries a +1 charge. The total is still zero.

    so it is the algebraic sum of total charges, not the total charges am i right?
