Question

Measurements of two electric currents are shown in the chart.

Answer 1

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.

Answer 2

The correct answer is:

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

The statement best compares the two currents.
