For an ideal full-wave rectified sine wave with peak value Vm, the average DC output voltage is?

  • AVm/pi
  • B2Vm/pi
  • CVm/2
  • DVm/sqrt(2)
Report an error
Correct Answer: B. 2Vm/pi
Explanation: Full-wave rectification makes both half-cycles positive, giving an average value of 2Vm/pi, approximately 0.637Vm.
Reference: Standard electronics: full-wave rectifier
