MCQ
Semiconductor is damaged by the strong current due to
  • A
    Lack of free electron
  • ✓
    Excess of electrons
  • C
    Excess of proton
  • D
    None of these
✓

Answer

Correct option: B.
Excess of electrons
When a strong current passes through the semiconductor it heats up the crystal and covalent bond are broken. Hence because of excess number of free electrons it behaves like a conductor.
