JEE MAIN - Physics (2023 - 25th January Evening Shift - No. 14)
Statement I : When a Si sample is doped with Boron, it becomes P type and when doped by Arsenic it becomes N-type semi conductor such that P-type has excess holes and N-type has excess electrons.
Statement II : When such P-type and N-type semi-conductors, are fused to make a junction, a current will automatically flow which can be detected with an externally connected ameter.
In the light of above statements, choose the most appropriate answer from the options given below
Statement I is incorrect but statement II is correct
Both Statement I and statement II are correct
Statement I is correct but statement II is incorrect
Both Statement I and Statement II are incorrect
Explanation
Statement I is correct but in statement II we cannot
detect the current through ammeter thus the
statement II is incorrect.
