An Introduction to the Capacitor
The nonconducting insulator serves to enhance the capacitor''s charge storage capacity. Anode and Cathode. The capacitor''s positive plate (as shown by the longer leg) is called an anode as it is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the insulator of the capacitor.

After removing two of the capacitors that read as shorter in circuit I found that the are not shorted and that the problem is elsewhere on the board. I can measure a dead short between the solder points with the capacitors removed. There are still other capacitors to remove which are read as shorted but I have a burning question as a hobbyist.

Why is the capacitor short-circuited in this example?
Any element for which terminals are connected by a conductor, as the capacitor in the figure, is said to be shorted. By having their shorted terminals, the voltage thereof is zero (more precisely, the potential difference between them), so that this element is not operational in the circuit, and can be removed for analysis. The other two capacitors are in series, hence that:
How can I quickly and safely discharge a charged capacitor …
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. If it only has 42V on it, these formulas say it will have a high current for a few nanoseconds, but the nanoHenry-scale parasitic inductances will limit the current and slow the discharge. …

What is capacitor? Principle working, types and how it works
Case 1# The area of the plates parallel to each other. The capacitor has an area of plates very much. So it is the greater the capacitance. Case 2# If the distance between the plates is greater, it will reduce the capacitance. Case 3# Change the dielectric substance. It causes the capacitance to change, as well.

For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the ...
