Question
Which statement is true regarding Inductor and capacitor
filter respectively used in the rectifier?Solution
In rectifier circuits, an inductor filter is always connected in series with the load, because an inductor opposes changes in current and thus smooths out the ripples. A capacitor filter is connected in shunt (parallel) with the load, because a capacitor stores and releases charge, reducing voltage ripples across the load.
