Question: Which of the following is the correct performance equation for mixed power-plants?
Options
A : Emaxsin?2=\Big[\frac{\lambda}{u}+\tau \Big]-\frac{1}{2}[u^2+u^{-2}]
B : Emaxsin?2=\Big[\frac{\lambda}{u}-\tau \Big]-\frac{1}{2}[u^2-u^{-2}]
C : Emaxsin?2=\Big[\frac{\lambda}{u}+\tau \Big]-\frac{1}{2}[u^2-u^{-2}]
D : Emaxsin?2=\Big[\frac{\lambda}{u}-\tau \Big]-\frac{1}{2}[u^2+u^{-2}]
