Question

What is the effect of adding a capacitor across load in a rectifier circuit?

Answer 1

Well, the capacitor that is connected parallel to the load resistance is used to smoothen the signal we get from the rectifier circuit. While converting AC to DC, we use therectifier circuit but the circuit does not completely convert the AC signal to DC signal.

Answer 2

Answer:

In a rectifier circuit, putting parallel capacitors across the load can smooth out voltage ripple. When the capacitance rises, the degree of smoothness also rises.

Explanation:

What happens if you connect a capacitor to a rectifier?

• The capacitor will charge and provide current to the load whenever the rectifier's voltage increases.
• The capacitor will be charged to the highest rectifier voltage value, which is indicated with the symbol Vm, at the end of the quarter phase, and then the voltage of the rectifier will begin to fall.
• The rectifier's full-wave rippling output is changed into a smoother DC output voltage by the smoothing capacitor.
• Now that we have several smoothing capacitor values fitted, we can evaluate how they affect the rectified output waveform by running the Partsim Simulator Circuit.

Thus, capacitors charge up until the voltage across the capacitor is equal to the externally applied voltage when they are linked across a direct current DC supply voltage.
