In this sense, I believe that we simply divide both currents.
[tex]\sf {power=voltage \ (x) \ current} \\ The \ power \ is ... 16 \\ Which \ divides \ from \ 2.[/tex]
Therefore, we do 16 / 2 = ... 8. And to check answer, we turn back to equation. 8 = voltage (x) (2) equals 16.
Answer: [tex]8A[/tex]
