To test for AC ripple on a PC power supply, you would set the volt/ohm meter for:

  • A.DC voltage scale
  • B.AC voltage
  • C.OHM scale
  • D.Farad scale

Answer: B

Correct answer: AC voltage

Ripple is the alternating component left on a direct current supply, so it is measured on the AC voltage range; the DC range would report only the average and hide it.
