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

Inductance and capacitance are effects that limit rate of change. Once things have settled out, there is no more change, and they have no further effect. 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 …

High-voltage capacitor in a low-voltage system

Quick question: is using a capacitor rated for high voltage (let''s say 35 V) in a system that, let''s say, supplies 5 V (like for LEDs or what have you) dangerous? Since it can store up to 35 V, will it like somehow store a bunch and then release it at once, damaging ...

How does a capacitor resist changes in voltage?

To see why it''s said that a capacitor ''resists'', or ''objects to'' changes in voltage at its terminals, it''s useful to compare its behaviour with a resistor (don''t confuse the ''resists'', meaning ''tries to stop'', with anything to do with the component ''resistor''). If …

Ceramic capacitor

A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical …
