But large capacitors can affect the stability of op-amps or switching regulators. And they can give rise to large inrush currents when power is first connected to a circuit. Even if the inrush can be accommodated, it may cause the power source Voltage to droop, and if other circuitry is attached to that power source, it may reset or malfunction ...

$begingroup$ This reason may be buried in one of the many good answers Some (only) regulators can be damaged by the output capacitor discharging back through the regulator if Vin is lowered to below Vcap. In particular, if power is turned off and other loads rapidly reduce Vin to near zero, or if Vin is set rapidly to zero by a fault or crowbar circuit, then …

A capacitor is made up of two conductive plates, which are separated by an insulating material called a dielectric. The plates are usually made out of materials like aluminium and copper, and the dielectric can be made out of materials like ceramic, plastic and paper. Capacitors can range in voltage, size and farads (F) of capacitance.

It''s labeled 16V 680uf, but I don''t have a capacitor with those exact specs. But as long as I find another capacitor with roughly the same capacitance, I should be able to substitute that, right? Q=CV Q=16v*680uf Q=10880C I have a ton of random junk that has various capacitors with other specs. For example, one is labeled 35v 470uf.
Trying to make due with one large cap will often imply that one will either have inferior high-frequency performance or else be spending more than one should. As for whether the total amount of capacitance can be too …

When the load is so heavy that the ripple is too large, you can use a bigger capacitor, because that smooths the line more. Therefore, it depends on the load what value you need for a capacitor. You can calculate the capacitance needed for the capacitor for a given mains frequency (not so important) and load current - however, I''d prefer testing around a bit …
The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates. In other words, capacitance is the largest amount of charge per volt …

The only feature that requires increasing the size of a capacitor is its voltage rating. Reasoning the other way around, You can trade off a smaller voltage rating of the capacitors in your design for a smaller package size (assuming the set of constraints above).
Capacitance, or capacitance rating, is the amount of energy that can be stored in the capacitor. The higher the capacitance rating, the more energy that can be stored. Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should select a new one with the same value.

Also note the energy stored in the capacitor, which will be deposited in the resistor which shorts it: U = 0.5 C V^2. As long as you''re dealing with the sorts of capacitors typically used with bread boards, you can probably short it with copper wire, as others have mentioned: 1 uF * 1mOhm = 1 ns discharge time.
Personal Injury: In extreme cases, the discharge of a large capacitor can cause severe burns, muscle contractions, or even cardiac arrest if the electrical current passes through the body. Fire Hazard: Capacitors store energy in the form of an electric field. If a charged capacitor is short-circuited or damaged, it can release this energy ...
The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller. This is especially helpful if you expect a high ripple current on the capacitors. Cost saving. Let''s say you need a large amount of ...
