'when frequency is increased why capacitance increases in a capacitor'?
Answer: Capacitance is unaffected by frequency; it does not change. Details: Capacitance is unaffected by frequency. In a capacitor, what increases with Frequency is Admittance (analogus to Conductance) . The capacitive Reactance is inversely proportional to Frequency. Therefore, when Frequency is increased, current flow may increase.
Function of dielectric in a capacitor?
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
How do you increase the value of a capacitor?
A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
What will happen when a dielectric slab is inserted in the parallel plate capacitor?
(a) Charge Will increase (b) Potential difference will stay the same (c) Capacitance will increase (d) Stored energy will decrease
In pn junction the depletion region capacitance increase with reverse bias or decrease?
any capacitance is given by equation C = (epsilon * A/ d) where d is distance between two plates, thus as d reduces C increases. Now, in depletion region as we increase reverse bias, the depletion region width increases. Now consider depletion region as a parallel plate capacitor, with positive charges on n side and negative charges on p side. Thus, as reverse bias increases, d of junction capacitance increases thus capacitance reduces. On other hand, as reverse bias reduces, d of junction capacitance reduces, thus capacitance increases. -Amey Churi
What happens to capacitance if voltage is increased?
If voltage is increased, capacitance remains constant. Capacitance is determined by the physical properties of the capacitor, such as plate area, distance between plates, and permittivity of the material, and is not affected by changes in voltage applied across the capacitor.

Will capacitence be increased with increase in the charges?
Definitely not possible. Capacitance is given by an expression C = epsilon x A / d Since charge is not present the capacitance cannot be increased or decreased by the charge placed
Doubling the plate area of a capacitor will?
increase the capacitance of the capacitor by a factor of two. This is because capacitance is directly proportional to the area of the plates.
What should we do to increase the capacitance of a capacitor?
Not much if it is a fixed capaitor. If it is a variable capacitor, rotating the shaft to mesh the two sets of plates more closely will increase the capacitance.

The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
What will be the effect on ripple factor if the value of capacitor is reduced?
Ripples will increase if capacitance is decreased.
How do you increase the value of a capacitor?
A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
How does the size of an electrolyte capacitor vary with its capacitance value?
A: Capacitance vary directly with the area applied the bigger the area the bigger the capacitor. There is another element that will increase the size that is the rating of the capacitor voltage since more material will have to be used to insulate the plates
What is the role of a dielectric in enhancing the capacitance of a parallel plate capacitor?
A dielectric in a parallel plate capacitor helps increase the capacitance by reducing the electric field strength between the plates, allowing more charge to be stored.
What will happen to phase angle if the the value of capacitor is increase?
in a series RC circuit phase angle is directly proportional to the capacitance
What will happen when a dielectric slab is inserted in the parallel plate capacitor?
(a) Charge Will increase (b) Potential difference will stay the same (c) Capacitance will increase (d) Stored energy will decrease
