Explanation:
When checking AC voltage with a voltage meter:
1. Set the meter to the AC voltage setting on the appropriate range.
2. Connect the red probe to the hot/live wire.
3. Connect the black probe to the neutral wire or the ground.
Ensure that you have a firm and secure connection with the wires to obtain an accurate voltage reading. Always follow safety precautions and, if unsure, consult a professional electrician.
