Answer:

you didn't say if its a parallel or a series circuit

Explanation:

If it's a series circuit

V =IR

[tex]v = 13 \times 3(4) \\ v = 13 \times 12\\ v = 156v [/tex]

However in parallel

calculate the Rp which will be

[tex]rp = \frac{1}{4} + \frac{1}{4} + \frac{1}{4} \\ rp = \frac{3}{4} [/tex]

so now you can say V=IR

[tex]v = \frac{3}{4} \times 13 \\ v = 9.75v[/tex]
