A 1 mA, 100 ohm meter movement is to measure 1 A full scale. The required shunt resistance is approximately?

  • A0.100 ohm
  • B1.00 ohm
  • C10 ohm
  • D100 ohm
Report an error
Correct Answer: A. 0.100 ohm
Explanation: Meter voltage at full scale is 0.001×100=0.1 V. Shunt current is 0.999 A, so Rsh=0.1/0.999≈0.100 ohm.
