A transducer is modeled with a current source Is and a parallel resistance Rs. The current
at the terminals of the source is measured to be 9.975 mA when an ammeter with an internal resistance of 20 Ω is used.
(a) If adding a 2-kΩ resistor across the source terminals causes the ammeter reading to fall to 9.876 mA, calculate Is and Rs.
(b) What will the ammeter reading be if the resistance between the source terminals is changed to 4 kΩ?
