A voltage amplifier intended to drive a low-resistance load with good voltage transfer should generally have?

  • ALow output resistance
  • BHigh output resistance
  • CZero input resistance
  • DNo power supply
Report an error
Correct Answer: A. Low output resistance
Explanation: Low output resistance minimizes voltage drop inside the amplifier when load current flows and improves voltage delivery to the load.
Reference: Standard analog electronics: amplifier output resistance
