14.8: Inductance (Summary)
14.3 Self-Inductance and Inductors Current changes in a device induce an emf in the device itself, called self-inductance, (displaystyle ε=−Lfrac{dI}{dt}), where L is the self-inductance of the inductor and (displaystyle dI/dt) …
Parasitic Inductance | Fundamentals | Capacitor Guide
Electric inductance is a property of all conductors. A change in the current flowing through the conductor creates (induces) a voltage in that conductor, as well as all nearby conductors. The induced voltage opposes the change in the current that induced the voltage. Inductance is a consequence of two laws of physics.
Capacitance vs Frequency | A Comprehensive Analysis
Near self-resonant frequency, inductive reactance cancels the capacitive reactance. Why do capacitors block DC but pass AC at high frequencies? Answer: With DC, frequency is zero, so reactance is infinite, blocking current.

Consider the two circuits shown in (Figure 1). The current in circuit 1, containing an inductor of self-inductance L, has a frequency f 1, while the current in circuit 2, containing a capacitor of capacitance C, has a frequency f 2.If we increase f 1 and decrease f 2, both bulbs grow dimmer.. If we keep f 1 and f 2 constant, we can achieve the exact same effect …

23.12: Inductance
The minus sign is an expression of Lenz''s law, indicating that emf opposes the change in current. Units of self-inductance are henries (H) just as for mutual inductance. The larger the self-inductance (L) of a device, the greater its opposition to any change in current through it. ... A capacitor stores the high voltage for later use in ...
14.5 Oscillations in an LC Circuit – University Physics Volume 2
It is worth noting that both capacitors and inductors store energy, in their electric and magnetic fields, respectively. A circuit containing both an inductor (L) and a capacitor (C) can oscillate without a source of emf by shifting the energy stored in the circuit between the electric and magnetic fields.Thus, the concepts we develop in this section are directly …
What really causes series inductance of capacitors?
This leads to self-inductance for any conductor with a varying current. As a capacitor is a low impedance at AC (the precise amount depends on frequency of course) then a real capacitor looks like …

That induces an emf across the solenoid, which will in turn have an effect on the current through it! This process is known as self-inductance. We actually define self-inductance in the same way that we defined mutual …

A charged capacitor of capacitance (C) is connected in series with a switch and an inductor of inductance (L). The switch is closed, and charge flows out of the capacitor and hence a current flows through the inductor.

14.3: Self-Inductance and Inductors
Since self-inductance is associated with the magnetic field produced by a current, any configuration of conductors possesses self-inductance. For example, besides the wire loop, a long, straight wire has self-inductance, as does a coaxial cable.

Figure 23.37 These coils can induce emfs in one another like an inefficient transformer. Their mutual inductance M indicates the effectiveness of the coupling between them. Here a change in current in coil 1 is seen to induce an emf in coil 2. (Note that "E 2 E 2 induced" represents the induced emf in coil 2.)
