Inductance, L is actually a measure of an inductors "resistance" to the change of the current flowing through the circuit and the larger is its value in Henries, the lower will be the rate of current change.

Capacitor in a superconducting circuit
$begingroup$ While you can specify that there is no inductor, you can''t actually specify that there is no inductance.Since the circuit encloses a non-zero area, there is necessarily self-inductance even if you assume an ideal capacitor (physical capacitors also have non-zero inductance, i.e., they are self-resonant).

Self-inductance
Self-inductance is the property of a coil or circuit that causes it to oppose changes in electric current passing through it, creating an induced electromotive force (EMF) in response to that change. This phenomenon is central to understanding how inductors behave in various circuits, influencing current growth and decay, energy storage, and interactions with other inductive

By knowing this inductance, one can calculate the resonance frequency of the capacitor geometry so that an appropriate capacitor value can be used to lower the power bus impedance for a certain frequency range (figure 2) (e.g., the clock frequency or its harmonics). 0-7SO3-SO15-V9S/$10.~10 0 1998 IEEE 1

6 FAQs about [Self-inductance circuit with capacitor]
How do you measure the self inductance of a capacitor?
I'll update my answer about the loop areas. The easiest way to measure the self inductance of a capacitor is to use it to shunt a signal being supplied from some modest impedance signal generator (like 50 or 600 ohms, whatever test gear you have access to). Vary the signal frequency, and measure the voltage across the capacitor.
Do all capacitors have equivalent series inductance?
Doing some research in selecting capacitors for high frequency applications, concept of equivalent series inductance comes up a lot. Apparently all capacitors have this parasitic inductance which appears in series with the capacitance of the component.
Does a capacitor act as an inductor?
You did read that correctly; the capacitor is now acting as an inductor. A 1 inch track at 4 thou (quite common) has about 5nH of inductance, for reference. This is the reason decoupling devices need to be so close to the actual power pin being decoupled. A device that is even as little as 1/2 inch away at these frequencies may as well not exist.
Why do capacitors have a parasitic inductance?
Apparently all capacitors have this parasitic inductance which appears in series with the capacitance of the component. If the ESL is high, in high frequencies this inductive reactance can even cancel out the capacitive reactance, and the cap essentially acts as a resistor which blocks DC. But why is the ESL so significant?
Who invented the self-capacitance of coil inductance?
The first time the question of self-capacitance of the coil inductance was raised by J.C. Hubbard in 1917. S.Butterworth, all known innovator and designer of frequency filtering circuits (remember Butterworth filters) in 1926 proposed a formula for the calculation, but it had serious limitations and could not count short coil.
Do electrolytic capacitors have a lot of inductance?
When it comes to electrolytic capacitors, I found one explanation: It was explained that as the cap is basically a long piece of foil rolled, there is definitely a lot of inductance since the roll of foil acts kind of like a coil. But I don't think this makes sense at all: It's not like the current travels along the foil!
