Assertion :-(A) semiconductors are solids with conductivites in the intermediate range from`10^(-6)-10^(4) ohm ^(-1)m^(-1)` Reason :-(R ) internmediate conductivity in semiconductor Is due to partially filled valence band .A. If both assertion and reason and true and reason is the correct explanation of assertion.B. If both assertion and reason and true and reason is not the correct explanation of assertion.C. If assertion is true but reason is false.D. If both assertion and reason are false. |
Answer» Correct Answer - C Conductance of semiconductors lies between metals and insulators, i.e., in therange of `10^(-6)` to `10^(4)ohm^(-1)m^(-1)` |
