JEE Mains Model Paper 22

The circuit will have inductive nature if ω >

1

√LC

Hence (a) is false. Also if circuit hasinductive nature the current will lag behind voltage. Hence (d) is also false
If ω =

1

√LC

the circuit will have resistance nature. Hence (b) is false.
cos ϕ =

R

√R2+(ωL− 1 ωC )2

= 1
ωL =
