A full wave rectifier circuit consists of two p - n junction diodes, a centre-tapped transformer, capacitor and a load resistance. Which of these components remove the ac ripple from the rectified output?

Options

  1. ALoad resistance
  2. BA centre-tapped transformer
  3. Cp - n junction diodes
  4. DCapacitor

Correct answer

D. Capacitor

Step-by-step solution

The design of full wave rectifier is as shown below. The capacitor in the initial part is uncharged. That means no voltage difference exists between the plates of the capacitor. So when the voltage is turned on, the charging of the capacitor happens immediately. During this conduction period, the capacitor charges to the maximum value of the input supply voltage. The capacitor stores a maximum charge exactly at the quarter positive half cycle in the waveform. At this point, the supply voltage is equal to the capaci
