摘要:
The need for a strict definition of fundamental units of measurement is pointed out. The fact that the ampere is defined by an equation in terms of other previously defined quantities requires that it be defined in terms of those quantities. This would give the ampere the unit ofnewton12, and would make the permeability unitless. The instructional value of this analysis is pointed out by showing the ease with which the undergraduate student may balance, dimensionally, equations involving electrical quantities.
