Answer:

6 V

Explanation:

We can solve the problem by using Ohm's law:

[tex]V=RI[/tex]

where

V is the voltage in the circuit

R is the resistance

I is the current

In this problem, we know the current, [tex]I=2 A[/tex], and the resistance, [tex]R=3 \Omega[/tex], therefore we can find the voltage in the circuit:

[tex]V=RI=(3 \Omega )(2 A)=6 V[/tex]
