Current Source The operational amplifier can make an excellent current source, as shown in figure 5. In this configuration, the load is inserted in the feedback loop. By adjusting the potentiometer and hence $V_{in}$ the current through the load resistor ($R_L$) can be adjusted. Questions 12 V $V_{in}$ +\ R\ $R_L$ I Figure 5. Op amp current source. 7. Determine I in terms of R, $R_L$, and $V_{in}$ 8. Does the current through the load depend on the resistance of the load?
