Basics of Electric Circuits

Circuit Elements: Passive, Active, and Linear

Description

Circuit elements are the building blocks of an electric circuit. An electric circuit is the connection of these elements. In this context, circuit elements are often grouped by how they behave and whether they supply energy.

One major group is passive elements. These elements do not generate ener...

电路元件是电路的基本构成单元。它们可以分为有源元件和无源元件。

有源元件可以产生能量,而无源元件则吸收能量。

有源元件的示例包括电压源或电流源,而电阻器、电容器和电感器则是无源元件的示例。

电路元件可进一步分为线性或非线性两类。

如果一个电路或元件的激励与响应遵循叠加性和齐次性原理,则该电路或元件被视为线性的。

假设一个电压 v1 导致反应 i1,以及一个电压 v2 导致反应 i2若该元件对电压之和的响应等于各响应之和, 那么它满足叠加原...
