What happens to the potential difference between the plates of a capacitor as the thickness of the dielectric slab increases?(a) Increases(b) Decreases(c) Remains the same(d) Becomes zero |

Answer» The correct answer is (b) Decreases Explanation: When a dielectric is introduced between the plates of a capacitor, its potential difference decreases. New potential difference= potential difference without dielectric-potential difference of dielectric. Hence as the thickness of the dielectric slab increases, a larger value is subtracted from the original potential difference. |
