Question

Suppose that we are designing an amplifier, using an op amp. What problems are associated with using very small feedback resistances? With very large feedback resistances?

Expert Solution

Step 1

Given:

Suppose on designing an amplifier, using an op amp. To explain the problems those are associated with using very small feedback resistances and with very large feedback resistances.

Step 2

The large currents results in excessively very small resistances due to the load. It results in exceeding the capacity of the op-amp. It involves the creation of excessive heat. The over loading of power supply will create heat problems.
