Which part of PCB circle for capacitor is positive? [closed]
Electrolytic capacitors usually have a stripe down one side (with minus symbols on it) that identifies the negative leg. You have several other capacitors in-situ on that board - and can see the light/dark board marking under them. Use them to identify light or dark as negative. From the pic, I believe dark is negative.
Can we build capacitors on a PCB board?
However, you can use some capacitors on the edges of your board, and distribute their voltage across the board using two copper planes acting as a capacitor. The discrete capacitors paralleled with your PCB capacitor can act as one nearly perfect lumped capacitor, giving your fast logic or power design the warm fuzzies.

Electrolytic Capacitor Failure and How it Affects Circuits
The higher the temperature, the more fluid the electrolyte is and the more mobile the ions are. Technicians may have noticed that a circuit board may fail when cold but works when warmed up. This is because the capacitors'' ESRs all reduce when warm. Circuit boards in refrigerators and freezers may prematurely fail because of this.
How Capacitors Work
In this blinking LED example circuit, the voltage across the capacitor is interpreted as either a 1 (HIGH) or a 0 (LOW) by the NOT gate. The output becomes the opposite of the input. So if the input is LOW, the output is HIGH. When the output is HIGH, the output voltage will start charging the capacitor so that it eventually also ends up HIGH.
