Inductance
השראות הדדית
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 ...
השראות עצמית
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, ...
חישוב השראות עצמית
The self-inductance of a circuit, often simply called the inductance, is a purely geometric factor that depends only on the circuit component's ...

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 ...
אנרגיה בשדה מגנטי
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 ...
אנרגיה המאוחסנת בכבל קואקסיאלי
A coaxial cable consists of a central copper conductor used for transmitting signals, followed by an insulator shield, a metallic braided mesh that ...
מעגלי RL
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 ...
צמיחה ודעיכה נוכחית במעגלי RL
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 ...
השוואה בין מעגלי RL ו- RC
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 ...
מעגלי LC
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. ...
תנודות במעגל LC
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 ...
מעגלים מסדרת RLC
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 ...
מעגל RLC כמתנד לח
An RLC circuit combines a resistor, inductor, and capacitor, connected in a series or parallel combination.
Consider a series RLC circuit. Here, the ...
