Question
A simple diode rectifier has ‘ripples’ in the output wave which makes it unsuitable as a DC source. To overcome this one can use
Both of the mentioned situations will work
A capacitor in series with a the load resistance
A capacitor in parallel to the load resistance
None of the mentioned situations will work
Solution
A capacitor in parallel to the load resistance
In a simple diode rectifier, the output is not a perfect DC but contains some AC components or ripples. To smooth out these ripples and get a more stable DC output, a capacitor is used. The capacitor is connected in parallel with the load resistance. This is because a capacitor in parallel stores the energy when the voltage increases and releases it when the voltage decreases, thus smoothing out the voltage ripples. A capacitor in series would not have the same effect as it would block the DC component of the output. Therefore, the correct answer is "A capacitor in parallel to the load resistance".
