Question

on reducing potential across or capacitor,it's capacitance of an object​

Answer 1

Answer:

The strength of electric field is reduced due to presence of dielectric and if the total charge on the plates is kept constant then the potential difference is reduced across the capacitor plates. In this way dielectric increases the capacitance of capacitor.

Answer 2

On reducing potential difference across a capacitor, its capacitance increases.

Explanation:

• Capacitance of a capacitor is defined as electric charge stored per unit potential difference applied across its end.

                                              $C = \frac{Q}{V}$

• Capacitance is directly proportional to charge (Q) and inversely proportional to potential difference (V).

• The SI unit of capacitance is Farad (F).
• Any object that has the capacity to get charged and store charge is a capacitor, hence is the name.

• Because of such importance of this device, there are ways to increase the capacity of the capacitor. This is visible by another formula of capacitance that is C = Aε/d .
• We see that C is directly proportional is A and inversely proportional to d.
• Increasing the area of the capacitor plate and/or decreasing the distance between the capacitor plate shall increase the capacitance of the device.
