Polyester film capacitor do they have a direction a positive or negative?

All capacitors are essentially charge holding components that build up a charge on either side of two plates, and then disperse it later. By nature they are not polar, so, no, they do not have a direction.

Is a cathode positive or negative in capacitor?
Depending on the capacitor we are using it will have a cathode.For example if we take a unicapacitor(it will allow current on both sides) it will have a negative and a bi capacitor it will not have negative
When a capacitor is being discharged in which direction does positive charge flow?
The 'conventional current' flows out of the positive side of the charged capacitor, and into the negative side. However, even though we never talk about it, we know that the things that actually carry the physical current around are the negatively charged electrons, and we know that when a capacitor is discharging, the electrons are flowing out of the negative side and into the positive side.
Do ac capacitor have positive and negative polarity?
both
How can friction be positive and negative?
Friction can be negative or positive depending on the direction in which your measures are positive.
Is a net loss a negative or a positive?
You can consider any direction as positive, and the opposite direction as negative. However, in this case it is customary to call a gain "positive", and a loss "negative".
Why capacitor does not store alternate current but store direct current?
Because Alternet current has both positive as well as negative cycle capacitor does not conduct for negative cycle of the Alternet current and DC all are positive cycle thats why it capacitor conduct for DC not for AC
What is the net charge on the charged capacitor?
there is no net charge on the capacitor because nomber of positive and negative charge and negetive are equal.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
How do you charge a capacitor?
You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead. Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.
What is capacitor polarized?
A polarized capacitor is one which has a polarity, positive on one terminal, negative on the other. This makes it superficially look like a battery. In use, the capacitor has its positive voltage always higher than that on the negative terminal, it matters that this is the case and this gives rise to the term polarized. This sort of capacitor is commonly found in power supply filters.
Why the capacitor has two positive and negative plats in it?
if your on apex get off this f@#king now
Why was the capacitor discharging current negative?
When a capacitor is discharging, current is flowing out of the capacitor to other elements in the circuit, similar to a battery. Current flowing out of an element, by convention, is defined as negative current, while current flowing into an element, such as a resistor, is defined as positive current. Thus a discharging capacitor will always have a negative current.
