Questions
Match the items given in Column I with the items given in Column II.
Column I | Column II | ||
A. | Mg in solid state | 1. | p -type semiconductor |
B. | MgCl2 in molten state | 2. | n-type semiconductor |
C. | Silicon with phosphorus | 3. | Electrolytic conductor |
D. | Germanium with boron | 4. | Electronic conductor |
detailed solution
Correct option is A
A. →(4) B. →(3) C. → (2) D. →(1)A. Mg in solid state show electronic conductivity due to the presence of free electrons hence, it is known as electronic conductor.B. MgCl2,in molten state show electrolytic conductivity due to the presence of ions in molten state.C. Silicon doped with phosphorus contain one extra electron due to which it shows conductivity under the influence of electric field and is known as p-type semiconductor.D. Germanium doped with boron contain one hole due to which it shows conductivity under the influence of electric field and is known as n-type semiconductor.Similar Questions
