The bridge rectifier circuit gives an output similar to that of a full wave rectifier. However, it consists of four

A series inductor filter utilizes the basic property of a inductor by which it opposes any change in the current

The Shunt Capacitor Filter comprises of a large value capacitor, which is connected in parallel with the load resistor.
