Assertion (A): The conductivity of p...
Assertion (A): The conductivity of p type semiconductor is higher than that of intrinsic semiconductor.
Reason (R): The addition of donor impurity creates additional energy levels below conduction band.
Both A and R are true and R is correct explanation of A
Both A and R are true but R is not a correct explanation of A
A is true but R is false
A is false but R is true
Correct answer is B
A refers to type semiconductor while R refers to n type semiconductor. Both A and R are correct but independent.
