Question

If the input frequency of a full wave rectifier is $50\text{Hz AC}$. Its output frequency is

• A. $50\text{Hz}$ pulsating $\text{DC}$
• B. $100\text{Hz}$ pulsating $\text{DC}$
• C. $200\text{Hz}$ pulsating $\text{DC}$
• D. $500\text{Hz}$ pulsating $\text{DC}$

Answer 1

The correct option is B $100\text{Hz}$ pulsating $\text{DC}$

In full wave rectifier, two diodes are used. Hence, each input cycle will be rectified and output will be obtained with twice the input frequency.

Hence, output frequency will be $100\text{Hz}$ pulsating $\text{DC}$ means option $\left(\text{B}\right)$ is obtained.
