Answer:

Step-by-step explanation:

Here we need to use Ohm's Law, because we have electric current, voltage and resistances. This law state: $V=IR$

So, first we need to calculate the total resistance to then find the voltage. The resistances can be placed in two ways: in parallel, in series.

The pair 4 and 8 ohms are parallel, so we solve:

$R_{T}=\frac{1}{R_{1}}+\frac{1}{R_{2}}$

$\frac{1}{R_{T}}=\frac{1}{4}+\frac{1}{8}=\frac{8+4}{32}=\frac{12}{32}=\frac{3}{8}$

Which is, $R_{T}=frac{8}{3}$

Now, this total resistance of parallels ones is placed in series with the 3 ohm resistance, in this case we just sum, because they are in series:

$R=3+\frac{8}{3}=\frac{9+8}{3}=\frac{17}{3}=5.67 ohm$

Now that we have the total resistance of the circuit, we use the Ohm's Law:

$V=IR\\V=(0.6A)(5.67ohm)=3.4 Volt$

Therefore, the right answer is B.
