To determine which of the given equations explains the relation between amperes (I), watts (W), and volts (V), we need to identify the correct formula that relates these electrical units.
Amperes (I) represent the current, watts (W) represent the power, and volts (V) represent the voltage. The correct equation that connects these three variables is:
[tex]\[ I = \frac{W}{V} \][/tex]
This means that the current (I) in amperes is equal to the power (W) in watts divided by the voltage (V) in volts.
Now, looking at the provided options:
1. [tex]\( I = \frac{W}{V} \)[/tex] - This matches the correct relationship.
2. [tex]\( 1 = W \times V \)[/tex] - This does not represent the correct relationship between these variables.
3. [tex]\( I = W + V \)[/tex] - This equation is also incorrect as it suggests an addition rather than a division.
4. [tex]\( 1 = W - V \)[/tex] - This is not a correct relationship either, as it suggests a difference being equal to 1, which is not relevant to the given units.
Therefore, the correct equation explaining the relation between amperes (I), watts (W), and volts (V) is:
[tex]\[ I = \frac{W}{V} \][/tex]
