Does the direction of the current change when the capacitor
Yes. 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.

Conversely, if the AC source is at -0.5 V, while the capacitor is at 0.7 V, current will flow in the positive direction while the voltage source is negative. So there could be situation where the capacitor overpowers the voltage source and current flows in a direction opposite to the voltage source''s direction.

6 FAQs about [Capacitor positive and negative current direction]
Do non polarized capacitors have a positive or negative terminal?
Non-polarized capacitors do not have a positive or negative terminal and can be connected to a circuit in any polarity. For optimal performance, you must orient polarized capacitors in the correct direction since they have positive and negative terminals, making them essential components.
Do capacitors have a positive and negative polarity?
Capacitors, especially electrolytic ones, have a positive and negative terminal. It's crucial to connect them correctly to avoid damage. Incorrect polarity can lead to the capacitor overheating, leaking, or even exploding. The longer lead is usually positive. Always refer to the datasheet or circuit diagram for specific polarity markings.
How to identify capacitor polarity?
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.
How do you know if a capacitor is positive or negative?
Electrolytic capacitors, a type of polarized capacitor, usually have clear markings indicating the positive (anode) and negative (cathode) terminals. The negative terminal is typically marked with a minus (-) sign, a series of minus signs, or a colored stripe. The positive terminal, on the other hand, is often longer than the negative one.
How does a capacitor work?
Taking electron current, and putting a capacitor in the circuit, the charging current flows from the negative terminal of the voltages source to the negative terminal of the capacitor, and from the positive terminal of the capacitor to the positive terminal of the voltage source. It effectively flows from negative to positive across the capacitor.
What happens if the polarity of a capacitor is reversed?
If the polarity is reversed, it can lead to the breakdown of the insulating oxide layer, potentially causing the capacitor to fail or even explode. On the other hand, a non-polarized capacitor, also known as a bipolar capacitor, doesn’t have a specific positive or negative terminal. This means it can be installed in any direction in a circuit.
