A. P=IV
Explanation
Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.
the electric powe can be written as follows:
[tex]\begin{gathered} P=IV \\ P=I^2R \\ P=\frac{V^2}{R} \\ where \\ P\text{ is the electrical powe} \\ I\text{ is the current} \\ V\text{ is the voltage} \\ R\text{ is the resistance} \end{gathered}[/tex]
therefore, according to the given choices, the answer is
A. P=IV
