It must be emphasized that the linear resistor is an idealized circuit element;it is a mathematical model of a physical device.''Resistors'' may be easily parchased or manufactured ,but it is soon found that the voltage-current ratio of this physical device is reasonably constant only within certain ranges of current,voltage,or power and depends also on temperature and other environmental factors.We shall usually refer to a linear resistor as simply a resistor ,using the longer term only when the linear nature of the element needs emphasis.Any resistor that is nonlinear woill always be described as such.Nonlinear resistors should not necessarily be considered as undesirable elements.

必须强调一个理想化的线性电阻是电路元件,它是一个物理设备的数学模型.“电阻”可以很容易parchased或制造,但它很快就会发现,这比物理设备薄膜是只在一定范围内相当稳定的电流、电压或功率,也依赖于温度及其他环境因素.我们将通常指一种线性电阻只是电阻、使用较长的任期只有当线性性质的元素需要强调.这是任何电阻非线性woill总是被描述为如此.非线性电阻不应该被认为是不受欢迎的元素.
