Why does a capacitor act like a short-circuit during a current
As to whether an impulse can show up against a capacitor or inductor with only a step source, the answer is it depends entirely on what part of the impulse you are looking for. If you are looking for the voltage across an inductor, for example, it will most definately show up. If you were looking for a current through the inductor however, no
Capacitor / inductor resonance
Since, in a simple LC circuit, the capacitor and inductor have the same voltage across, as the voltage increases on the capacitor, the current changes at a faster rate. When the current is zero, the capacitor (and inductor) voltage is maximum which means that the current is changing most rapidly there, i.e., the current goes through zero and changes direction.

So, when we look to find what the "resistance" analogs are for inductors and capacitors in this phasor domain, we would take the relationships I = C(dV/dt) and V = L(dI/dt) for capacitors and inductors, and plug in the time-dependent factor of e i omega t to get I_phasor = iomegaCV_phasor and V_phasor = iomegaLV_phasor for the capacitor and inductor

6 FAQs about [Capacitor becomes inductor]
Why does an inductor behave like a capacitor?
As the frequency increases, the impedance of the inductor increases while the impedance of the parasitic capacitor decreases, so at some high frequency the impedance of the capacitor is much lower than the impedance of the inductor, which means that your inductor behaves like a capacitor. The inductor also has its own resonance frequency.
What are capacitors & inductors?
Capacitors and inductors are important components in electronic circuits and each of them serve unique functions. Capacitors store energy in an electric field, while inductors store energy in a magnetic field. They have different applications and characteristics, such as energy storage, filtering, and impedance matching.
Why does a real world capacitor behave like an inductor?
Why does a real world capacitor behave like an inductor at frequencies above its self-resonant frequency? I've come across some graphs comparing the impedance of a capacitor over frequency and it understandably declines as frequency increases -- up until a certain point. Afterwhich, the impedance begins to increase, like an inductor.
Why does a capacitor act as a lead in an inductor?
The inductor acts like an open circuit initially so the voltage leads in the inductor as voltage appears instantly across open terminals of inductor at t=0 and hence leads. simply remember capacitor rises voltage from 0 to high,so at intitally at ov capacitor acts as short ckt and for high voltage cap acts as open ckt, reverse in case of inductor
What does a capacitor & inductor look like?
So in the long-term, steady-state, capacitors and inductors look like what they are; they act like you'd expect them to act if you knew how they were constructed, but didn't know capacitance or inductance even existed. An inductor is a wire. After it saturates the core, it behaves like a short circuit. A capacitor is a gap between two conductors.
Why does a capacitor act like a short circuit at t 0?
Capacitor acts like short circuit at t=0, the reason that capacitor have leading current in it. The inductor acts like an open circuit initially so the voltage leads in the inductor as voltage appears instantly across open terminals of inductor at t=0 and hence leads.
