**How can we increase the capacitance of capacitor?** Note: From the formula of the capacitance, we can see that capacitance is also proportional to the area of the plates, and inversely proportional to the distance between the plates. Hence, the capacitance can also be increased by either **increasing the area of the plates or decreasing the distance between the plates**.

**What factors affect the capacitance of a parallel plate capacitor?** The capacitance of a parallel plate capacitor depends on **area of each plate, dielectric medium between the plates and distance between the plates**.

**Why does capacitance of parallel plates increase?** **area of the plate is decreased distance between the plates increases area of the plate is increased dielectric constant decreases**. Solution : In a parallel plate capacitor the capacity of capacitor . <br> `C = (K epsi_(0)A)/(d) i.e., C propA` <br> The capacity of capacitor increases if area of the plate is increased.

**How dielectric increases the capacitance?** The dielectric placed between the plates of the capacitor reduces the electric field strength between the plates of the capacitor, this results in a small voltage between the plates for the same charge. The capacitor stores more charge for a smaller value of voltage. Therefore the capacitance increases.

## How can we increase the capacitance of capacitor? – Additional Questions

### Does increasing charge on capacitor increase capacitance?

**the charge**

**Increasing Q does not change the capacitance at all**. The capacitance is a constant because it is determined by how the capacitor looks like. With this, Q = C ΔV tells us that the potential difference across the capacitor doubles when the charge on each plate doubles.

### Which situation will result in a larger capacitance between two parallel plates?

Hence, the capacitance between two parallel plates increases **when there are a bigger plate area and a shorter distance between the plates**.

### How is the capacitance of a parallel plate capacitor decreased?

The capacitance is inversely proportional to the distance between the plates. Hence, the capacitance of a capacitor decreases **when the plates are farther apart**.

### How does the capacitance of a parallel plate capacitor vary with distance between the plates?

Solution : Capacitance is **inversely proportional** to the distance between the plactes or thickness of the dielectrics between the plates.

### How does the capacitance of a parallel plate capacitor change when the distance between the two plates is decreased by half?

Hence, if the distance between the plates of a parallel plate capacitor is halved then the capacitance of the capacitor will become **twice the initial capacitance**.

### What happens to capacitance when voltage is increased?

If there is an increase in the voltage **the capacitance will be less** since voltage and capacitance are inversely proportional.

### Why does capacitance decrease as distance increases?

**When the plates are far apart the potential difference is maximum** (because between the plates you travel through a larger distance of the field, and the field also isn’t cancelled out by the field of the other plate), therefore the capacitance is less.

### What will happen to the capacitance if we increase separation between plates?

Solution : When the plate separation is increased, the charge stored in the capacitor remains same and **the capacitance decreases**.

### On what factors does the capacitance of capacitor depend?

Solution : **Area of each plate, distance between the capacitor plates and the intermeditae medium** are the factors on which the capacitance depends.

### Does capacitance depend on charge and voltage?

The capacitance for a given capacitor will strictly be a constant. **Capacitance does not depend on the voltage of the charging source or the charges of the plates**. Capacitance depends only on the physical characteristics of the capacitor like the area of the plates and the distance between the plates.

### What will be the effect on capacitance if the distance between the parallel?

C=dAϵk i.e. capacitance is **inversely proportional** to distance between the plates.
