Physics · Operational Amplifiers
In a standard ideal Op-amp voltage-to-current converter circuit where the load resistance RL is connected in the feedback loop to the inverting terminal, and the input voltage Vs is applied to the non-inverting terminal through a resistor Rs (or vice-versa forming a voltage-controlled current source), what is the load current I0 independent of the load resistor RL?
- 1Vs × (1Rs + 1RL)
- 2Vs × RLRs(RL + Rs)
- 3VsRs✓
- 4VsRL
Correct answer
VsRs
