Wave rectifier is used to convert the ac voltage source into dc voltage source. The p-n junction diode and step-down transformer are used to form the rectifier. The full wave bridge rectifier uses four diodes to rectify the ac voltage.
The circuit diagram is shown below:
The circuit can be changed into the half wave rectifier by removing the diodes D2 and D4 because they are responsible for rectifying the voltage when it is in negative cycle. When these two diodes will be removed the positive cycle of ac voltage will be rectified by diodes D1 and D3 as they are in forward bias. The output received will be due to these two diodes only and it will be similar to the half wave rectifier output.

Gautam went for a vacation to the village where his grandmother lived. His grandmother took him to watch ‘nautanki’ one evening. They noticed a black box connected to the mike lying nearby. Gautam’s grandmother did not know what that box was. When she asked this question to Gautam, he explained to her that it was an amplifier.
(i) Which values were displayed by the grandmother? How can inculcation of these values in students be promoted?
(ii) What is the function of an amplifier?
(iii) Which basic electronic device is used in the amplifier?
(i) Describe the working principle of a solar cell. Mention three basic processes involved in the generation of emf.
(ii) Why are Si and GaAs preferred materials for solar cells?
