Step 1: Understanding the problem.
In AC circuits, ripples refer to unwanted fluctuations in the DC output after rectification. To remove these ripples, we need a component that smooths out the variations in the signal.
Step 2: Correct component to remove ripples.
To remove ripples in an AC circuit, a filter capacitor (or simply a capacitor) is typically connected in parallel with the load. This smooths out the fluctuations in the output by providing a path for the AC components to pass through while allowing the DC component to be filtered and stabilized.
Step 3: Conclusion.
A capacitor is commonly used to remove ripples in an AC circuit.
