Question
Assertion : Semiconductors do not Obey's Ohm's law.
Reason : Current is determined by the rate of flow of charge carriers.
✓

Answer

(e) The assertion is not true. In fact, semiconductor Obeys Ohm's law for low values of electric field $(\sim 10 \cdot \mathrm{V} / \mathrm{m})$. Above this, the current becomes almost independent of electric field.
