The chart shows the voltage of four electric currents.

Voltage of Currents
\begin{tabular}{|l|l|}
\hline Current & \multicolumn{1}{|c|}{Volts (V)} \\
\hline W & 9.0 \\
\hline [tex]$X$[/tex] & 1.5 \\
\hline [tex]$Y$[/tex] & 3.0 \\
\hline [tex]$Z$[/tex] & 4.5 \\

\end{tabular}

Which is best supported by the data in the chart?

A. Current W flows at a higher rate than Current [tex]$Z$[/tex].
B. Current [tex]$Y$[/tex] flows at a lower rate than Current [tex]$X$[/tex].
C. Current [tex]$X$[/tex] has a lower potential difference than Current [tex]$Y$[/tex].
D. Current [tex]$Z$[/tex] has a greater potential difference than Current W.



Answer :

Let's go through the given statements one by one and compare the voltages provided in the chart to determine which is best supported by the data.

Here are the voltages for reference:
- Voltage of Current W: 9.0 V
- Voltage of Current X: 1.5 V
- Voltage of Current Y: 3.0 V
- Voltage of Current Z: 4.5 V

1. Current W flows at a higher rate than Current Z.
- Comparing the voltages of W and Z:
- Voltage of W: 9.0 V
- Voltage of Z: 4.5 V
- Since 9.0 V is greater than 4.5 V, this statement is True.

2. Current Y flows at a lower rate than Current X.
- Comparing the voltages of Y and X:
- Voltage of Y: 3.0 V
- Voltage of X: 1.5 V
- Since 3.0 V is not lower than 1.5 V, this statement is False.

3. Current X has a lower potential difference than Current Y.
- Comparing the voltages of X and Y:
- Voltage of X: 1.5 V
- Voltage of Y: 3.0 V
- Since 1.5 V is less than 3.0 V, this statement is True.

4. Current Z has a greater potential difference than Current W.
- Comparing the voltages of Z and W:
- Voltage of Z: 4.5 V
- Voltage of W: 9.0 V
- Since 4.5 V is not greater than 9.0 V, this statement is False.

So, the statements compare as follows:

- Current W flows at a higher rate than Current Z: True
- Current Y flows at a lower rate than Current X: False
- Current X has a lower potential difference than Current Y: True
- Current Z has a greater potential difference than Current W: False

Therefore, the statements that are best supported by the data in the chart are:
- Current W flows at a higher rate than Current Z.
- Current X has a lower potential difference than Current Y.
