The chart shows the voltage of four electric currents. 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.

The correct option is Current W flows at a higher rate than Current Z.

Explanation: To answer this question, we will require Ohm's law.

Ohm's Law states that the current flowing through a conductor across two points is directly proportional to the voltage difference across that two points.

Mathematically,

where, V = voltage

I = Current

R = resistance

For the given question, assuming that the resistance is constant. So, the current is directly proportional to the voltage.

Hence, as the current W is greater of all the given currents so, it will flow at a higher rate.

Therefore, the correct answer is Current W flows at a higher rate than Current Z.
