What are the behaviors of capacitors and inductors at time t=0?

Basically, a capacitor resists a change in voltage, and an inductor resists a change in current. So, at t=0 a capacitor acts as a short circuit and an inductor acts as an open circuit. These two short videos might also be helpful, they look at the 3 effects of capacitors and inductors:

Why does a capacitor act like a short-circuit during a current

A step function hitting a induction results in an instant change in voltage while the current flowing through remains at zero. This is exactly the same behavior as an open circuit. Now, both of these components start changing over time. Given enough time, the capacitor starts acting as an open circuit and the inductor as a short-circuit. But

Why does a capacitor act as an open circuit under a DC circuit?

You can see from the other answers why it appears that way mathematically. Physically, it''s because it is an open circuit! Consider the most basic form of a capacitor, the parallel plate capacitor.All real capacitors are similar to this, though it may be hard to see it because there are many layers, the layers are coiled up or there is more complexity to the layers.

Capacitor short circuit and open circuit measurement

6 FAQs about [Capacitor short circuit and open circuit measurement]

What happens if a capacitor is a short circuit?

(A short circuit) As time continues and the charge accumulates, the capacitors voltage rises and it's current consumption drops until the capacitor voltage and the applied voltage are equal and no current flows into the capacitor (open circuit). This effect may not be immediately recognizable with smaller capacitors.

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.

Are capacitors open circuits or shorts?

At DC, ideal capacitors act like open circuits and linear approximations are generally only accurate for small deviations from the linearization point, which is the DC point in this case. Hence, it seems like it would make more sense to treat capacitors as open circuits, not shorts. So why do we do the opposite?

What is the difference between an open circuit and a capacitor?

An open circuit will not admit any current even when a voltage is applied whereas a capacitor will accept arbitrarily high currents with the voltage only changing over time in response to currents. @user107063 indeed. it's a vast simplification of a complex situation.

What is a capacitor and how is It measured?

Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).

Are coupling capacitors a short circuit?

When you treat them as short circuits you are making the assumption the have negligible reactance at the frequencies you are interested in. This is usually true for the coupling capacitors in an amplifier circuit. There are also capacitors you treat as open circuits because they have very large reactance at the frequencies of interest.
