Inductance
互感
Inductance is the property of a device that tells us how effectively it induces an emf in another device. In other words, it is a physical quantity that ...
自感应
Mutual inductance arises when a current in one circuit produces a changing magnetic field that induces an emf in another circuit. On the other hand, ...
自感的计算
The self-inductance of a circuit, often simply called the inductance, is a purely geometric factor that depends only on the circuit component's ...
电感
An inductor, also known as a choke, is a circuit component created to have a specific inductance. Inductors are among the crucial circuit components used ...
磁场中的能量
If a magnetic field is sustained, there must be a current in a closed circuit or loop, implying some energy has been spent in creating the field. If this ...
同轴电缆中存储的能量
A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that ...
RL 电路
An RL circuit consists of a resistor and an inductor and may have a source of emf connected to it. The inductor in the circuit helps to prevent rapid ...
RL 电路中的电流增长和衰减
The current growth and decay in RL circuits can be understood by considering a series RL circuit consisting of a resistor, an inductor, a constant source ...
RL 和 RC 电路之间的比较
An RC circuit consists of resistance and capacitance, while in an RL circuit, capacitance is replaced by an inductor. RL and RC circuits are first-order ...
LC 电路
An LC circuit consists of an inductor and a capacitor, either in series or parallel. Consider a charged capacitor connected with an inductor in series. ...
LC 电路中的振荡
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and ...
RLC 系列电路
An RLC series circuit comprises an inductor, a resistor, and a charged capacitor connected in series. When the circuit is closed, the capacitor begins to ...
RLC Circuit as a Damped Oscillator
An RLC circuit combines a resistor, inductor, and capacitor, connected in a series or parallel combination.
Consider a series RLC circuit. Here, the ...
