A benchtop de power supply acts as an ideal 4 A current source as long as its terminal voltage is below 10 V. Beyond this point, it begins to behave as an ideal 10 V voltage source for all load currents going down to 0 A. When connected to an ideal rheostat, find the load resistance value at which maximum power is transferred, and the corresponding load voltage and current.
A
Short, ∞ A. 10 V
B
Open, 4 A, 0 V
C
2.5 Ω, 4 Α, 10 V
D
2.5 Ω. 4 A, 5V

Correct : c
