The chart shows the voltage of four electric currents. A 2-column table with 2 rows titled Voltage of Currents. The first column labeled Current has entries W, X, Y, Z. The second column labeled Volts (volts) has entries 9.0, 1.5, 3.0, 4.5. 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.
