The Correct Option is B
Solution and Explanation
To remove ripples in an AC circuit, a capacitor is usually connected in parallel with the load resistance. This arrangement helps smooth out the variations in the output voltage by allowing the capacitor to filter out high-frequency ripple components.
Step 1: Understanding ripple reduction.
Ripples are unwanted variations in the output signal, often seen in the rectified output of an AC-to-DC converter. The purpose of adding a capacitor in parallel is to smooth these ripples by providing a low-pass filter effect, allowing the DC component to pass while filtering out the AC ripple components.
Step 2: Capacitor in parallel.
When a capacitor is connected in parallel with the load resistance, it charges during the peaks of the AC cycle and discharges during the valleys, thus reducing the fluctuations (ripples) in the output voltage.
Step 3: Conclusion.
Therefore, the correct method to remove ripples is to connect a capacitor in parallel with the load resistance.
Final Answer: (B) Capacitor in parallel with load resistance
