Let's analyze and compare the two electric currents, X and Y, as per the measurements given in the chart.

First, let's understand the measurements:

Current X:
- Volts (V) = 1.5
- Amperes (A) = 7.8

Current Y:
- Volts (V) = 9
- Amperes (A) = 0.5

We need to compare the potential difference (volts) and the rate of charge flow (amperes) of these two currents. Let's break down the comparison step-by-step:

1. Potential Difference (Voltage):
- Current X has a voltage of 1.5 V.
- Current Y has a voltage of 9 V.
- Comparison: Current Y has a greater potential difference since 9 V is greater than 1.5 V.

2. Rate of Charge Flow (Current in Amperes):
- Current X has an amperage of 7.8 A.
- Current Y has an amperage of 0.5 A.
- Comparison: Current X has a greater rate of charge flow since 7.8 A is greater than 0.5 A.

Based on these comparisons:
- Current Y has a greater potential difference (voltage).
- Current X has a greater rate of charge flow (amperes).

Therefore, the option that best compares the two currents is:

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

However, upon reviewing the given detailed result of the problem, it confirms that:

- Power of Current X is 11.7 watts.
- Power of Current Y is 4.5 watts.

And the final comparison result is:

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

So, the correct option corresponding to this analysis is:

Current [tex]\(Y\)[/tex] has a greater potential difference, and the charges flow at a slower rate.
