Measurements of two electric currents are shown in the chart. which best compares the two currents? a. current x has a greater potential difference, and the charges flow at a slower rate. b. current y has a greater potential difference, and the charges flow at a slower rate. c. current x has a greater potential difference, and the charges flow at a faster rate. d. current y has a greater potential difference, and the charges flow at a faster rate.

Answer

Correct answer is B. Current Y has a greater potential difference, and the charges flow at a slower rate.

Explanation

Current Y has a potential difference of 9 volts and current X has a potential difference of 1.5 volts. This tell us that current Y has a greater potential difference.

A current is the rate of low of charge.  Current X is 7.8 A which is bigger than current Y which is 0.5 A. This tell us that current X flows faster than current Y.

From these statements, we conclude that Current Y has greater potential difference than current X and the charges in current Y flow at a slower rate. The correct answer is B.
