This doesn''t make sense to me. The positive part is positive and the negative part is negative regardless of which direction the current flows. If current is flowing into the positive part then the device the plug is attached to is receiving power (would be a little against standard use of these kind of plugs). $endgroup$ –

Modest surface mount capacitors can be quite small while the power supply filter capacitors commonly used in consumer electronics devices such as an audio amplifier can be considerably larger than a D cell battery. A sampling of capacitors is shown in Figure 8.2.4 . Figure 8.2.4 : A variety of capacitor styles and packages.
On schematics, I''ve seen V-in and ground, I''ve also seen V-in, ground, and a separate trace connecting to the negative terminal. Then, we move to AC. There''s a hot wire (positive), a neutral wire, and ground. I ~assume~ that in an AC circuit, positive correlates to positive, neutral to negative, and ground to ground.
Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor. These type of capacitors are only used in DC applications.
By combining both of these with separate output smoothing capacitors it is possible to get an output voltage of nearly double the peak AC input voltage, figure 6.7. This also provides a tap in the middle, which allows use of such a circuit as …

Axial cans will have a line on one side with arrows pointing to the negative lead, or an indented band that designates the positive lead. Surface mount tantalum chips will have a line and/or a notch on the positive end. Axial will have a notch on the positive side. Radial has either an arrow or positive indicator above the positive lead.
Filter capacitor: It is connected between the positive and negative poles of the DC power supply to filter out the unnecessary AC components in the DC power supply and smooth the DC power. Generally, a large-capacity electrolytic capacitor is often used, and other types of small-capacitance capacitors can also be connected in the …
capacitor needs to operate in AC, in other words, it must be able to charge and discharge following the mains voltage in both positive and negative half cycles. 2.3 Completing the capacitive power supply design We have now an operating AC/DC converter with only four components, and it is much more efficient (at least compared
Reverse Polarity means that the positive and negative outputs of a power supply have been connected to the wrong terminals on a PCB. This mistake can cause catastrophic component failure in the form of smoking parts, exploding capacitors, and occasionally an electrical fire.
The passive sign convention states that in components in which the conventional current variable i is defined as entering the device through the terminal which is positive as defined by the voltage variable v, [2] [4] the power p and resistance r are given by [5] [6] [7] = and = / In components in which the current i is defined such that positive current enters the …
The polarity of a capacitor refers to the orientation of the component''s terminals, indicating which terminal should be connected to the positive pole and which to the negative pole of a power supply. This polarity is essential, since if the capacitor is connected incorrectly, it can be damaged or even cause problems in the circuit in which it ...

Capacitor polarity refers to the specific orientation of a capacitor''s positive and negative terminals within an electrical circuit, determined by its internal structure of two conductive plates separated by …
The graph in Figure 23.44 starts with voltage across the capacitor at a maximum. The current is zero at this point, because the capacitor is fully charged and halts the flow. Then voltage drops and the current becomes negative as the capacitor discharges. At point a, the capacitor has fully discharged (Q = 0 Q = 0 on it) and the voltage across ...
Caution may be required with other sorts of supply, as their negative terminal may be connected to a metal case, and thence to "Safety Ground/Earth Ground". Another solution would be to use an isolated DC-DC converter - connect its positive output to the negative terminal of your main supply, then its negative terminal is your negative …
Capacitor polarity defines the positive and negative terminals of a capacitor. it is important since the capacitor can connected with the circuit in accurate polarity. if the capacitor is attached in incorrect polarity, can …
Before making a negative voltage circuit, we need to understand what a negative voltage is. In a dual rail power supply, it is easy to notice three outputs which are positive, ground and negative voltage. The ground is the reference voltage for the circuit i.e., 0V. Positive and negative voltages are approximately equal in value but opposite.

It depends on the voltage ratings of the capacitor and the power supply - and how much current the power supply can deliver. If the the power supply voltage is higher than the rated voltage of the capacitor, then the capacitor will be damaged. Some capacitors will fail and short circuit when you exceed the voltage rating.
To figure out capacitor polarity the stripe on an electrolytic capacitor tells you the negative end. For axial leaded capacitors (in which the leads come out of the opposite ends of the capacitor), there may be an arrow that points to the negative end, symbolizing the flow of charge.
