インダクタンス
相互インダクタンス
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 ...
自己インダクタンス
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, ...
自己インダクタンスの計算
The self-inductance of a circuit, often simply called the inductance, is a purely geometric factor that depends only on the circuit component's ...
インダクタ
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 ...
磁場中のエネルギー
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 ...
同軸ケーブルに蓄えられたエネルギー
A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that ...
RL回路
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回路の電流成長と減衰
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回路とRC回路の比較
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回路
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回路の発振
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シリーズ回路
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 ...
減衰発振器としてのRLC回路
An RLC circuit combines a resistor, inductor, and capacitor, connected in a series or parallel combination.
Consider a series RLC circuit. Here, the ...
