What is the efficiency of power transfer when maximum transfer of power occurs?
Understand the Problem
The question is asking about the conditions under which maximum power transfer occurs, specifically focusing on the efficiency of that power transfer.
Answer
50%
The efficiency of power transfer when maximum transfer of power occurs is 50%.
Answer for screen readers
The efficiency of power transfer when maximum transfer of power occurs is 50%.
More Information
The maximum power transfer theorem states that to maximize power transfer, the load impedance should match the source impedance. However, this results in only 50% efficiency because half the power is dissipated in the source.
Tips
A common mistake is assuming maximum power transfer leads to maximum efficiency. In this case, efficiency is only 50% because power is equally divided between the source and the load.
