SUMMARY
An operational amplifier (op-amp) can be configured to supply a constant current to a load by utilizing a feedback loop that includes a current sensing resistor. This configuration ensures that the op-amp adjusts its output to maintain a steady current, regardless of variations in load resistance. Key components in this setup include the op-amp itself, a feedback resistor, and a current sensing resistor, which collectively form a negative feedback system to stabilize the current output.
