What would be the expected amperage measurement if you clamped your meter around both wires in a two wire circuit?

When clamping a meter around both wires in a two-wire circuit, the expected amperage measurement would be zero because the two current flows in the wires are equal and opposite. This results in the cancellation of the magnetic fields created by the currents in each wire.

In a two-wire circuit, one wire typically carries current in one direction while the other wire carries the return current in the opposite direction. When these currents flow simultaneously, their magnetic fields will oppose each other, leading to a net measurement of zero amperage. This is because the amp clamp measures the sum of the currents passing through it, and in this case, those currents effectively cancel each other out.

It’s important to note that if you had clamped around just one wire, you would measure the total current flowing in that specific wire. But by clamping around both wires, the clamp doesn’t detect any net current, hence resulting in a reading of zero amperage.
