Q1:

Assertion (A): A semiconductor strain gauge is more accurate than a resistance strain gauge. Reason (R): The gauge factor of a semiconductor strain gauge is about 100 where as the gauge factor of a resistance strain gauge is only about 2.

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 correct explanation of A

C A is true R is false

D A is false R is true

ANS:A - Both A and R are true and R is correct explanation of A

Higher gauge factor results in better accuracy.
