Q1: Assertion (A): If a wave v = A₁ + A₂ sin ωt is applied to a pure capacitor the current wave is
i = A₃ sin(ωt + 90°) Reason (R): A capacitor presents infinite impedance to dc.

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

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

Since capacitor presents infinite impedance to dc, voltage component A₁, does not cause any current.
