ASE Question Of the Month

Which is correct?

You’re correct if you answered A!

Reading the same voltage at either end of the grid is the same as reading equal voltage on either side of a light bulb or any other electrical load. It indicates a fault in the ground side of the circuit so Technician B is incorrect. Technician A, however, is correct. As the voltmeter lead moves closer to the ground side of the grid line, the resistance of the grid line will increase, creating an increasing voltage drop.
