负载功率随负载变化的规律

Nonmonotropic relationship between load power change and load change

针对电路中负载改变时 ,所耗功率变化的不确定性 ,研究了负载功率随负载变化的规律 .经理论分析和实验结果表明 :负载功率的变化不仅与负载的变化有关 ,同时 ,原负载电阻和电源内阻之间的关系也影响着负载功率的变化趋势 ,因此 ,负载功率变化随负载的变化呈现非单调性规律 .

The paper deals with the regularity between load power change and load change based on the nondeterminacy of the load power consumption change, when the load changes in the circuit. The result of the experiment and the theoretical analysis prove that the change of load power is not only connected with the change of load, but also with the relationship between the internal resistance of the power source and the resistance of the original load. Therefore, the regularity between load power change and load change appears nonmonotropic.
