1.4 A signal source that is most conveniently represented by its Norton equivalent form has is = 10 µA and Rs = 100 kΩ. If the source feeds a load resistance RL, find the current io that flows through the load for RL = 1 kΩ, 10 kΩ, 100 kΩ, and 1 MΩ. Also, find the largest permissible value of RL for which the load current is at least 80% of the source current.
9.9 µA; 9.1 µA; 5 µA; 0.9 µA; 25 kΩ
