fast signals, the capacitor "looks" like a short-circuit. But after a while the capacitor''s reservoirs fill, the current stops, and we notice that there really is a break in the circuit. For slow signals, a capacitor "looks" like an open circuit. What is fast, and what is slow? It depends on the capacitor and the rest of the circuit.

6 FAQs about [Capacitors and Inductance]
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 do we use inductors over capacitors?
We opt for inductors over capacitors because inductors hold energy within a field whereas capacitors store energy in a field. Depending on the circuit's needs, like energy storage, filtering or impedance matching an inductor might be a choice, than a capacitor. What is the difference between resistor capacitor and inductor?
What is the difference between capacitor and inductance?
Capacitance and inductance are two fundamental properties of electrical circuits that affect the flow of current and the storage of energy. Capacitance refers to the ability of a component, such as a capacitor, to store electrical energy in an electric field. It is measured in farads and is characterized by its ability to resist changes in voltage.
How do capacitors and inductors store energy?
Furthermore, the energy storage mechanisms of capacitors and inductors differ. Capacitors store energy in an electric field, while inductors store energy in a magnetic field. This distinction leads to variations in their energy release characteristics and response times.
What are the characteristics of ideal capacitors and inductors?
Delve into the characteristics of ideal capacitors and inductors, including their equivalent capacitance and inductance, discrete variations, and the principles of energy storage within capacitors and inductors. The ideal resistor was a useful approximation of many practical electrical devices.
Are capacitors better than inductors?
Capacitors are generally smaller and cheaper compared to inductors, making them more suitable for compact electronic devices. Inductors, with their larger size and higher cost, are often used in applications where higher inductance values and higher power handling capabilities are required.
