Signals and Systems
14.

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.

Both A and R are correct and R is correct explanation of A
Both A and R are correct but R is not correct explanation of A
A is true, R is false
A is false, R is true
Answer: Option
Explanation:

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