Signals and Systems - Engineering

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.
