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.

A what will move in the direction of the arrows on the electric field lines?
A positive charge will move in the direction of the arrows on the electric field lines. Electric field lines show the direction a positive test charge would move if placed in the field.
How can a capacitor be charged using a battery charger?
To charge a capacitor using a battery charger, you connect the positive terminal of the battery charger to the positive terminal of the capacitor, and the negative terminal of the battery charger to the negative terminal of the capacitor. The battery charger will then supply a voltage to the capacitor, causing it to store electrical energy.
How can one determine the direction of the electric field?
To determine the direction of the electric field, you can use a positive test charge. The direction of the electric field is the direction in which a positive test charge would move if placed in that field.
If you place a charge into an electric field it will move in the direction indicated by the electric field lines?
Yes, a charge placed in an electric field will experience a force and move in the direction of the electric field lines if it is positive, or opposite to the direction if the charge is negative. The force on the charge is proportional to the charge itself and the strength of the electric field at that location.
What is the formula for calculating the charge stored in a capacitor?
The formula for calculating the charge stored in a capacitor is Q CV, where Q represents the charge stored in the capacitor, C is the capacitance of the capacitor, and V is the voltage across the capacitor.
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
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.
What is discharging direction of capacitor?
When a capacitor discharges the discharge current flows in the opposite direction to the current used to charge it.
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.
How fast can a battery charge a discharged capacitor in the absence of a resistor?
Depends on the size of the battery and the capacitor. If both are small enough to fit in your hand, then some fraction of a second.
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.
How do you use a diode to charge your saltwater capacitors with ac voltage?
Simply include the diode in one of the AC supply lines to your capacitor. (not sure what a salt water capacitor is) but, all capacitors only store charge, which is discharged as a DC current.
Does a charged capacitor have an identical level of charge on both plates?
No, in a charged capacitor, one plate has a positive charge and the other plate has a negative charge. The magnitude of the charges on the plates is equal and opposite, resulting in a net charge of zero for the entire capacitor.
A what will move in the direction of the arrows on the electric field lines?
A positive charge will move in the direction of the arrows on the electric field lines. Electric field lines show the direction a positive test charge would move if placed in the field.
How can a capacitor be charged using a battery charger?
To charge a capacitor using a battery charger, you connect the positive terminal of the battery charger to the positive terminal of the capacitor, and the negative terminal of the battery charger to the negative terminal of the capacitor. The battery charger will then supply a voltage to the capacitor, causing it to store electrical energy.
Why is the direction of dipole moment is from negative to positive charge?
The direction of the dipole moment is from the negative charge to the positive charge because it represents the vector pointing from negative charge towards positive charge, illustrating the net charge distribution within the molecule or system. This convention is commonly used to describe the direction of the dipole moment vector.
How does an RC work?
The resistor allows a slow charge to enter the capacitor. When this charge reaches a certain point the circuit activates and forces the capacitor to discharge. Once discharged the circuit reverses itself and starts the charge over again. The larger the cap and/or resistor the lower the frequency because it takes longer to charge the cap.
