a. Determine V for the current source of given figure(a) with an internal resistance of 10 kΩ.
b. The source of part (a) is approximated by an ideal current source in given figure (b) since the source resistance is much larger than the applied load.
Determine the resulting voltage V for figure(b), and compare it to that obtained in part (a). Is the use of the ideal current source a good approximation?
