If you used KVL and treat the capacitor as a source, you could think of it as something like this: Where Vs V s is the capacitor voltage and the other element is the resistor. Here the source follows the PSC too, that's why you see Is I s going into the source. From the circuit you can see that Is = −I I s = − I.
Thank you. Your node "above" the resistor and capacitor is labeled as having a voltage V. The convention is that current will flow from a more positive potential V to a more negative voltage, in this case ground. So the direction of current on your capacitor C is backwards according to convention, i.e., it's drawn in the wrong direction.
So the direction of current on your capacitor C is backwards according to convention, i.e., it's drawn in the wrong direction. You can do this but your first equation (according to KCL and your convention) should be I =IC −IR I = I C − I R.
Visual identification is one of the quickest and easiest methods to determine capacitor polarity. It involves inspecting the physical markings on the capacitor and the circuit board. Here are some common indicators:
Yes. When a capacitor is charging, current flows towards the positiveplate (as positive charge is added to that plate) and away from the negativeplate. When the capacitor is discharging, current flows away from thepositive and towards the negative plate, in the opposite direction.
Visual Examples Leaded radial capacitors: The negative terminal is marked with a stripe or band running along the length of the body. PCB-mounted radial capacitors: Often show clear markings with a longer lead for the positive terminal and a band for the negative terminal. Identifying Markings Longer lead: Indicates the positive terminal.

When a capacitor is charging, current flows towards the positive plate (as positive charge is added to that plate) and away from the negative plate. When the capacitor is discharging, current flows away from the positive and towards the negative plate, in the opposite direction.
Once you assume a direction arrow, voltage drops across the resistors are plus on the side the arrow enters. Normal we assumed that the current flows from higher (more positive) to lower potential. In your example circuit, we see a 9V voltage source. Thus, we can assume that the current will flow out of the positive terminal of the voltage source.
If you look at each charge on the Capacitor plates, it appears that the -10C would start canceling the 10C between the Capacitors, and electrons would flow from the -5C plate to the 5C plate. Therefore electrons would flow following the RED arrow.
The conventional direction of current flow is along the direction of the motion of positive charges. In most cases, free electrons are responsible for current flow. Therefore scientists mentioned its direction by comparing the direction of electron flow. They said, Electric current flows in the opposite direction of the flow of free electrons.
This type of capacitor cannot be connected across an alternating current source, because half of the time, ac voltage would have the wrong polarity, as an alternating current reverses its polarity (see Alternating-Current Circuts on alternating-current circuits). A variable air capacitor (Figure (PageIndex{7})) has two sets of parallel ...

Damage to the capacitor: By reversing the polarity, a current can be generated in the opposite direction through the capacitor, which can damage its internal structure and reduce its useful life. Circuit problems: If the capacitor is connected incorrectly in a circuit, it can cause problems such as short circuits, failure of other components, or even damage the power supply.

Before delving into identifying capacitor polarity, let''s grasp the concept of polarity itself. In electronics, polarity refers to the positive (+) and negative (-) terminals of a component, indicating the direction of current flow. Capacitors, like other electronic components, possess polarity, denoted by their positive and negative terminals.
The electrons can''t flow across the dielectric material in the capacitor so they accumulate on the negative side. Meanwhile, electrons are drawn out of the other side to the positive terminal of the voltage source. This constitutes an "effective" flow through the capacitor.
A capacitor''s stored energy can be recovered by allowing its potential difference to push current through some external energy recipient. In such a case, with the capacitor now discharging, donating energy, that current must be in the direction in which it exits via the capacitor''s higher potential terminal, just like a battery.
