Answer:
[tex]3.0 \Omega[/tex]
Explanation:
Ohm's law states that the potential difference across a resistance is proportional to the current flowing through it, according to the equation:
[tex]V=RI[/tex]
where
V is the potential difference
R is the resistance
I is the current
In this circuit,
V = 12.0 V
I = 4.0 A
Solving for R, we find the resistance:
[tex]R=\frac{V}{I}=\frac{12.0}{4.0}=3.0 \Omega[/tex]
