Question

In a rectifier circuit, what is the purpose of adding a capacitor in parallel with the load resistance ($R_L$)?

Professor PC Thomas Classes · Answer

A capacitor acts as a filter. It charges to the peak voltage during the conduction half-cycle and discharges slowly through the load during the non-conduction half-cycle, thereby smoothing the pulsating dc into a steady dc.
