In the real scene
To measure the current, you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying current and ground wire. The current in two wires always flows in opposite directions, so the magnetic fields from the two wires canceling each other; therefore, the meter reads 0 A.
Grasp the individual current conductor to be measured and close the current clamp again. The measured conductor must be placed in the center of the clamp; otherwise additional errors will occur.
