| Effect of Dielectric on Capacitance |
|
|
| |
 |
| |
| When a dielectric slab tdue to polarisation). So, |
| |
| V = E0(d - t) + Et |

 |

 |
| |
 |
| |
| Clearly: C>Co |
| |
| This is expected because introduction of dielectric slab reduces the electric field and hence potential difference between the plates. Since, charge on capacitor plates is same, capacitance increases. |
