Answer:

For me I think it is A

Explanation:

Answer:

A) 6V

Explanation:

To solve this problem we need to use ohm's law

We have the resistance

[tex]Resistance=R=3ohms[/tex]

and the current:

[tex]Current=I=2A[/tex]

To find the voltage we use the following formula from ohm's law:

[tex]Voltage=(Current)(Resistance)[/tex]

so

[tex]V=I*R[/tex]

substituting the known values:

[tex]V=(2A)(3ohms)=6volts[/tex]

the voltage of the battery is 6V which is option A.
