Charge Conservation & Isolated Systems

Click For Summary
SUMMARY

Charge conservation in isolated systems maintains that the total charge remains constant, even when charged particles are created. In the case of pair production, where high-energy gamma radiation generates an electron and a positron, the number of charged particles increases, but the total charge remains zero. An electron has a charge of -1, while a positron has a charge of +1, resulting in an algebraic sum of zero. Thus, charge conservation is upheld through the balance of positive and negative charges, not the count of charged particles.

A isolated system in which number of charges present is always constant. Suppose a high energy gamma radiation enters into 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?
