Complete the statement
Conservation of charge means the total charge of an {0} system stays unchanged in time. Charging by friction is a {1} of charge, with no creation or {2} of it.
Conservation is a statement about isolated systems. Source: syllabus Physics Part I, Ch 1 Electric Charges and Fields.
