Maximum power transfer theorem:
This is a very important theorem. Most usually for analyzing electronic and communication networks where main consideration is to transfer maximum power to the load irrespective of the efficiency, this theorem is highly important.
A resistive load connected to a dc network receives maximum power when the load resistance is equal to the internal resistance of the source network as seen from load terminals.
As this theorem is very easy to understand, there is no need of a big clarification. You can simply understand the theorem. If you understood it, then you will understand the important of thevenin’s theorem. After determine the thevenin’s voltage, to transfer the maximum power to the load, we have to add the load resistance equal to the thevenin’s theorem.
So here onwards we will use this theorem with thevenin’s theorem.
