Which is best supported by the data in the chart? current w flows at a higher rate than current z. current y flows at a lower rate than current x. current x has a lower potential difference than current y. current z has a greater potential difference than current w.

There is no chart provided in this statement. However, the current that flows within an electrically charged item is dependent on how it is arranged. There are two kinds of current and these are, parallel and circuit currents. Current that flows in  parallel current is less than when it is farther away from the electric source; current that flows in a series current flows at a constant rate regardless of how far it is from the electrical source.
