\hline
\end{tabular}

Which best compares the two currents?

A. Current [tex]$X$[/tex] has a greater potential difference, and the charges flow at a slower rate.
B. Current [tex]$Y$[/tex] has a greater potential difference, and the charges flow at a slower rate.
C. Current [tex]$X$[/tex] has a greater potential difference, and the charges flow at a faster rate.
D. Current [tex]$Y$[/tex] has a greater potential difference, and the charges flow at a faster rate.



Answer :

To effectively compare the two electric currents, we must analyze the given data in the chart concerning Volts (potential difference) and Amperes (flow rate). Let's break down the information step-by-step:

1. Voltage Comparison:
- For Current \( X \), the voltage is \( 1.5 \) Volts.
- For Current \( Y \), the voltage is \( 9.0 \) Volts.

By comparing these values, we see that \( 9.0 \) Volts is greater than \( 1.5 \) Volts. Thus, Current \( Y \) has the greater potential difference.

2. Current (Flow Rate) Comparison:
- For Current \( X \), the current is \( 7.8 \) Amperes.
- For Current \( Y \), the current is \( 0.5 \) Amperes.

By comparing these values, we see that \( 7.8 \) Amperes is greater than \( 0.5 \) Amperes. Thus, Current \( X \) has the faster flow rate.

3. Comparing Characteristics:
- Current \( Y \) has the greater potential difference.
- Current \( X \) has the faster flow rate.

Given this analysis, the correct statement that best compares the two currents is:
Current [tex]\( Y \)[/tex] has a greater potential difference, and the charges flow at a slower rate.
