Answer:
6 V
Explanation:
In a circuit, the relationship between voltage, current and resistance is given by Ohm's law:
[tex]V=RI[/tex]
where
V is the voltage
R is the resistance
I is the current
In this circuit, we have
[tex]R=12.0\Omega[/tex] is the resistance
I = 0.500 A
so we can find the voltage of the battery by using Ohm's law:
[tex]V=(12.0 \Omega)(0.500 A)=6 V[/tex]
