#### Question

Answer in Brief

**Answer the following question.**

Draw the circuit diagram of a full-wave rectifier and explain its working. Also, give the input and output waveforms.

#### Solution

**Full-wave rectifier**Two diodes are used to give rectified O/P corresponding to both positive as well as negative half cycles.

When the voltage at A with respect to the center tap is positive, and the voltage at B is negative. Then, D_{1} is forward biased and D_{2} is reversed biased. Hence, D_{1} conducts and D_{2} does not. When the voltage of A becomes negative, then B becomes +ve. Therefore, D_{1} does not conduct and D_{2} conducts. Hence, we obtain output voltage during both the positive as well as negative half of the cycle.

Input and Output waveforms are shown below.
