To solve this problem, we have to use the following expression
[tex]V=\frac{P}{I}[/tex]Where P = 10.0 W and I = 2.0 A. Let's use these values to find the voltage (V).
[tex]\begin{gathered} V=\frac{10.0W}{2.0A} \\ V=5.0V \end{gathered}[/tex]It's important to know that 5.0 is equivalent to 5.0×10^0 because every power with a null exponent is equal to 1.
