The correct answer is B. AC voltage.
To test for AC ripple on a PC power supply, you would set the volt/ohm meter for AC voltage. This is because AC ripple is a type of noise that is present in the output voltage of a power supply. It is caused by the switching action of the power supply’s internal components. AC ripple can cause problems with sensitive electronic equipment, so it is important to test for it and make sure that it is within acceptable limits.
The other options are incorrect because they are not the correct settings for testing for AC ripple. DC voltage is the voltage that is present when there is no current flowing. OHM scale is the scale that is used to measure resistance. Farad scale is the scale that is used to measure capacitance.
Here are some additional details about AC ripple:
- AC ripple is a type of noise that is present in the output voltage of a power supply.
- It is caused by the switching action of the power supply’s internal components.
- AC ripple can cause problems with sensitive electronic equipment, so it is important to test for it and make sure that it is within acceptable limits.
- The correct setting for testing for AC ripple is AC voltage.
