Easier Analysis Method of the Maximum Power Transfer Law

Differential equation is usually used in analyzing and proving the maximum power transfer law in most electric and electronic textbooks.Complicated differential equation must be used in this way.So the way is difficult and the result is not intuitional.This paper puts forward an easier and more intuitional way which is based on calculating inequation and needn′t solve differential equation.This paper analyzes and proves the maximum power transfer laws of direct circuit and alternate circuit.In the actual teaching,quality of teaching is improved effectively.
