9. Below is shown a simple resistive current source. The resistive load is represented

by a 10 kΩ potentiometer. What is the current through the resistive load over the

full range of the potentiometer and what is the reading on the voltmeter over the

full range of the potentiometer? Does this circuit represent a reasonable constant

current source? Why or why not (explain)?

Please see the following PDF (Question #9) for the diagram of the circuit:

The only equations that I know that are useful here would probably just be Ohm's law and variants:

P=IV

V=IR

I=dQ/dt

Unfortunately, I don't know where to begin with this problem. The only true given is the voltage, so I don't know how to solve this problem.

Any help is appreciated!
