Formulate the law of conservation of electric charge.

The law of conservation of charge sounds as follows: the algebraic (that is, non-vectorial, the charge is a scalar quantity), the sum of the charges of a closed system remains constant (conserved). It is written as follows: q = q1 + q2 + q3 +… + qn = const. From the written expression it follows that the number of charges can be arbitrary (1, 100 or n), the essence of the law will not change from this. That is, no matter how many charges are in an electrically closed system, their sum will always be constant (constant).
