电源传输效率与负载最大功率的探讨

A search for the efficiency power transfer and the maximum efficacy of electricity loading

文章指出,当电源一定时,电路中负载消耗的电功率与负载大小有关,负载电阻与电源内阻相等时电路为匹配状态。电路中负载消耗电功率与电源传输效率之间是矛盾对立的关系,它们在电力线路与电子电路中有着不同的应用。

When electric source is certain, the loss of loading has to do with electric power in electric circuit. Loading electric resistance is equal to electric source internal resistance. The electric circuit is in a state of resistance matching. The relationship between the loss of loading and the efficiency of electric source is contradictory. They have different application in electric power circuit and electric circuit.
