Unformatted text preview: power s L = = P P η Thevenin equivalent cannot be used to calculate power efficiency in the original network. Maximum power transfer condition results in 50 percent efficiency in Thevenin equivalent, however much lower efficiency in the original circuit. Maximum Power Transfer -Example a) Find the value of R L that results in maximum power being transferred to R L . b) Calculate the maximum power that can be delivered to R L . c) When R L is adjusted for maximum power transfer, what percentage of the power delivered by the 360 V source reaches R L ? o 30 Ω 150 Ω 360 V R L o a b...
