    1. What is the effect as \(R_i\) is increased in the circuit of Figure 7.5.1?

    2. Does the load impedance play an appreciable role in setting the load current?

    3. What is the effect as \(R_f\) is decreased in the circuit of Figure 7.5.2?

    4. In practical voltage-source circuits, the load impedance can be too small, forcing the op amp into current limiting with resulting distortion. Are there similar limits in the current-source circuits?
