Why isn''t a 1 Farad capacitor equivalent to a wire in LTspice?
In SPICE, an AC analysis starts by doing a DC analysis to establish the operating point. In a DC analysis, any capacitor, no matter how large its value, is treated as an open circuit. So, if you replaced the wire connecting to the op-amp''s inverting input with a capacitor, in the DC analysis, you''d have no negative feedback. If the op-amp model ...

A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance.

The space between capacitors may simply be a vacuum, and, in that case, a …
Capacitor across an ideal current source
The capacitance of a capacitor tells you how much charge is required to get a voltage of 1V across the capacitor. Putting a charge of 1uC into a capacitor of 1uF will result in a voltage of 1V across its terminals. An ideal capacitor can take an infinite amount of charge resulting in an infinitely high voltage.
What are the behaviors of capacitors and inductors at time t=0?
Because capacitors store energy in the form of an electric field, they tend to act like small secondary-cell batteries, being able to store and release electrical energy. A fully discharged capacitor maintains zero volts across its terminals, and a charged capacitor maintains a steady quantity of voltage across its terminals, just like a ...
