Let Vs=10V, R1=2?, R2=2?, R3=3? and R4=1? in the circuit of Figure 4-1. Find the Thevenin (Vth, Rth) and Norton (IN, RN) equivalents between terminal a and a'. Which of the following statements is true?
A. For the load resistance, RL= 0.8 Ohm, the 10V independent voltage source delivers a maximum power of 0.3125 W to RL.
B. Vth=4 V and Rth=5 Ohm
C. IN=1.25 A and RN=1.2 Ohm
D. None of the above.
