Assertion (A): Clipping circuit controls the shape of the waveform by clipping or removing a portion of the applied wave.
Reason (R): It needs minimum three components namely an ordinary diode, a resistor and a capacitor.
Consider the following statements associated with the diode rectifier circuits:
1. The maximum reverse voltage, which can be applied before the breakdown point is reached, is called the “peak inverse voltage”.
2. In a full-wave rectifier, the current in each of the diode flows for the whole input signal cycle.
3. The ratio of direct or average value of the output to the effective value of AC component present in the rectifier output is called the “ripple factor”.
4. Availability of low-cost silicon diodes has made bridge circuit arrangement more economical than centre trapped transformer arrangement despite its requirement of four diodes:
Q. Which of the above statements are correct?
