用导线将电源和负载连接起来就构成电路.电源在工作时内阻如果不发生变化,我们把它称为线性电源,反之称为非线性电源.在解决电路计算问题时,电源和负载都是线性的,求解比较容易.电源和负载中有一个是非线性的,学生往往感到束手无策.在处理这类问题时,若能作出相关元件的伏安特性曲线,找出电路的工作状态,问题便会迎刃而解.一、负载由相同的非线性元件组成例1如图1所示为一个电灯两端的电压与通过
Connect the power and load with a wire to form a circuit. When the power supply at work does not change the internal resistance, we call it a linear power supply, otherwise known as non-linear power supply.In solving the circuit calculation problems, the power supply and load are Linear, easy to solve. One of the power supply and load is non-linear, students often feel helpless. In dealing with such issues, if you can make the relevant components of the volt-ampere characteristic curve, find out the working state of the circuit, the problem will be Able to solve. First, the load by the same non-linear components Example 1 shown in Figure 1 for a lamp across the voltage and through
