HC Verma Chapter 45 Problem 10

Problem Statement

In a half-wave rectifier the input is 50 Hz AC. What is the output frequency?

Key Concepts

Half-wave rectification

Relevant Formulas

f_out = f_in (one pulse per cycle)

Step-by-Step Solution

One pulse per full AC cycle. Output frequency = 50 Hz (same frequency, only positive half-cycles pass).

Final Answer

Output frequency = 50 Hz

Tips and Tricks

Only one half-cycle passes per cycle; efficiency = 40.6%.

Common Mistakes

Always use SI units. Check energy conservation accounts for all forms.
