Q1:

Assertion (A): In series R-L-C circuit, the current may lead or lag the voltage depending on the value of R. Reason (R): Phase angle of an R-L series circuit is tan-1 (ωL/R).

A Both A and R are true and R is correct explanation of A

B Both A and R are true and R is not the correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:D - A is false but R is true

The current may lead or lag the voltage depending on values of L and C.
