In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Note that two of these types—mica capacitors and flat molded paper capacitors—look similar. Both are flat, often with color coding dots to indicate the value. It is easy to tell them apart by checking the value. Mica capacitors have very small values, typically under .001 mfd., typically under .001 mfd.

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 …

When should I use a low ESR capacitor

When the AC source is low frequency (50 Hz, 60 Hz, 120 Hz...) the capacitors are physically large, and could tolerate high ESR (like, 1 ohm for a 1A supply with a 1000 uF filter capacitor). That''s because a one-amp ripple current only created one watt of heat, and a large (over a square inch of surface area) 1000uF capacitor can shed …
