Match the following :
| COLUMN I | COLUMN II | ||
| 1 | Knee voltage of Ge p-n junction diode | A | 0.7 V |
| 2 | Knee voltage of Si p-n junction diode | B | 0.3 V |
| 3 | Energy gap of Ge semiconductor | C | 1.1 eV |
| 4 | Energy gap of Si semiconductor | D | 0.7 eV |
Answer & explanation
Correct answer: option 1
Correctly matched pairs are :
| COLUMN I | COLUMN II | ||
| 1 | Knee voltage of Ge p-n junction diode | B | 0.3 V |
| 2 | Knee voltage of Si p-n junction diode | A | 0.7 V |
| 3 | Energy gap of Ge semiconductor | D | 0.7 eV |
| 4 | Energy gap of Si semiconductor | C | 1.1 eV |
Note that the knee voltage is voltage and is of the order of Volts and Energy gap is energy and is of the order of eV.
