Answer: 3 A
Explanation:
According to Ohm's law:
[tex]V=R.I[/tex]
Where:
[tex]V=9 V[/tex] is the voltage
[tex]R=3\Omega[/tex] is the resistance of the resistor
[tex]I[/tex] is the electric current (the value we want to find)
Isolating [tex]I[/tex]:
[tex]I=\frac{V}{R}[/tex]
[tex]I=\frac{9 V}{3\Omega}[/tex]
Finally:
[tex]I=3 A[/tex]
