a dc source has a voltage of 100 v and a sourse resistance of 50 ohms. what load resistance will maximise the power transfer?

Solution

According to maximum power transfer theorem ...maximum power transfered from source to load when ever sourse resistance is equal to load resistance.

Here given sourse resistance is given as 50 ohms

for maximum power transfer,,,,,, load resistance must be 50 ohms

so P_max = V² / 4R

= 100² / (4*50)

= 50 w
