Assertion (A): | The resistance of a photodiode decreases when light having photons of sufficient energy is incident on it. |
Reason (R): | When energetic photons fall on the \(\mathrm{p\text{-}n}\) junction of a photodiode, electron-hole pairs are created due to the breaking of the valence bonds. |
1. | (A) is True but (R) is False. |
2. | (A) is False but (R) is True. |
3. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
4. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
Statement I: | If the current through the diode increases, then the dynamic resistance decreases. |
Statement II: | If the temperature of the diode is increased, with the potential difference fixed, the dynamic resistance decreases. |
1. | Statement I is incorrect and Statement II is correct. |
2. | Both Statement I and Statement II are correct. |
3. | Both Statement I and Statement II are incorrect. |
