Q1: Assertion (A): Hall effect is used to find the type of semiconductor. Reason (R): When a specimen of semiconductor carrying current I lies in a magnetic field the force on electrons and holes is in opposite directions.A Both A and R are true and R is correct explanation of A
B Both A and R are true but R is not a correct explanation of A
C A is true but R is false
D A is false but R is true
ANS:A - Both A and R are true and R is correct explanation of A When a current. Carrying semiconductor is placed in a magnetic field charge inside the semiconductor experience a force which is perpendicular to both magnetic field and current. |
