Answer :
Final answer:
To test AC voltage with a multimeter, set the dial to the VAC option (c), symbolized by a 'V' with a wavy line on top (~), to measure alternating current voltage accurately and safely.
Explanation:
The proper multimeter dial setting when testing AC voltage is c) VAC. This setting allows the multimeter to measure alternating current voltage (AC voltage), which is represented on the dial by the symbol 'V' with a wavy line on top (~). When setting up the multimeter, ensure the red test lead is connected to the 'V' port and the black test lead to the 'COM' port, and then select the proper range on the dial for the voltage you expect to measure. It's essential to use the right setting to prevent damage to the multimeter and ensure an accurate measurement.
