Question

What is the maximum efficiency of full wave rectifier?

• A. 82.1%
• B. 72.8%
• C. 88.4%
• D. 81.2%

Hint:

A full wave rectifier's maximum efficiency is calculated using the formula \( \eta = \frac{P_{DC}}{P_{AC}} \), which yields 81.2%.

Answer 1

The Correct Option is C

The maximum efficiency of a full wave rectifier is 81.2%. This value is derived based on the theoretical calculation of efficiency in ideal conditions, where the rectifier is expected to convert the maximum amount of AC power to DC.
